Question

Add the polynomials. Type your answer into the box. Use a caret (^) before an exponent. Do not add any spaces. (ex. 2X^2-2X+2)

3x^2- x-8
7x^2-9x-1

Answer 1

Answer: To add the polynomials, we simply add the coefficients of the same degree terms. This gives:

(3x^2 - x - 8) + (7x^2 - 9x - 1) = 10x^2 - 10x - 9

Therefore, the sum of the polynomials is 10x^2 - 10x - 9.
