| 1. | Press 2nd adopted by x to convey up the “Poly” menu |
| 2. | Use the arrow keys to navigate to the “Enter” choice and press “enter” |
| 3. | Enter the coefficients of the second polynomial, beginning with the coefficient of the best diploma time period |
| 4. | Press the “down arrow” key to maneuver to the following coefficient |
| 5. | Proceed getting into the coefficients of the polynomial till you attain the fixed time period |
| 6. | Press “enter” after getting into the final coefficient |
Deciding on the End result Variable
Upon getting entered the 2 polynomials, you have to choose the variable the place you need to retailer the results of the multiplication. To do that, press the “VARS” button, adopted by the “STO>” button. You’ll then see a listing of variables. Use the arrow keys to focus on the variable you need to use, then press the “ENTER” button. The chosen variable might be displayed within the “Ans” area on the high of the display.
Suggestions for Deciding on the End result Variable
Listed below are some ideas for choosing the outcome variable:
| Tip | Description |
|---|---|
| Use a variable that isn’t already in use. | It will make it easier to keep away from overwriting vital information. |
| Select a variable identify that’s straightforward to recollect. | It will make it simpler to search out the outcome variable in a while. |
| Use the “Ans” variable. | This variable is routinely up to date with the results of the final calculation. It may be a handy strategy to retailer the results of the multiplication with out having to create a brand new variable. |
Evaluating the Multiplication
Upon getting entered the polynomial expressions into the calculator, you’ll be able to proceed to multiply them. To do that, press the “MATH” button, choose the “PRB” choice, after which select “5:POLY” from the menu. It will convey up the polynomial multiplication menu.
Within the “F(x)” area, enter the primary polynomial expression. Within the “G(x)” area, enter the second polynomial expression. The calculator will show the product of the 2 polynomials within the “RESULT” area.
Instance
As an instance we need to multiply the polynomials (x + 2) and (x – 3). We’d enter the next into the calculator:
| F(x) | G(x) | RESULT |
|---|---|---|
| x + 2 | x – 3 | x^2 – x – 6 |

Displaying the End result
After getting into the multiplication expression utilizing the steps outlined within the earlier part, you’ll be able to lastly consider the product and show the outcome. Here is find out how to do it:
1. Spotlight the multiplication expression: Use the arrow keys to maneuver the cursor over the whole expression.
2. Press the “ENTER” key: It will consider the expression and show the outcome within the subsequent line.
3. Perceive the outcome: The displayed result’s the simplified product of the 2 polynomials. It could be in factored type or expanded type, relying in your desire.
Instance: Multiplying the polynomials (x – 2)(x + 3) will yield the outcome x^2 + x – 6, which is the expanded type of the product.
Further Suggestions:
| Tip | Description |
|---|---|
| Use parentheses or brackets across the multiplication expression to make sure correct order of operations. | Prevents any confusion and ensures the proper product is calculated. |

Checking the Reply
Upon getting multiplied the polynomials, it is essential to confirm your reply. Here is how one can verify your work:
- Increase the expression manually: Use the distributive property to multiply every time period of 1 polynomial by every time period of the opposite polynomial, after which simplify the outcome. In case your reply matches the outcome you bought on the calculator, it is right.
- Use the “ANS” key: After multiplying the polynomials on the calculator, press the “ANS” key. The calculator will show the reply. Now, enter one of many unique polynomials, multiply it by the opposite polynomial, after which press the “ANS” key once more. If the outcome matches the reply you bought on the primary try, your reply is probably going correct.
- Test for components: Issue each the unique polynomials and the ensuing polynomial. For those who can issue all three polynomials in the identical method, it is a sign that your reply is right.
| Technique | Benefits | Disadvantages |
|---|---|---|
| Increasing manually | Very correct | Time-consuming and liable to errors |
| Utilizing the “ANS” key | Fast and simple | Potential for errors if you happen to make a mistake in getting into the second polynomial |
| Checking for components | Can verify correctness for some polynomials | Might not work for all polynomials |
Bear in mind, it is at all times apply to verify your solutions to keep away from errors and guarantee accuracy.
