Find the sum of these polynomials.
(x2 + x + 9) + (7x2 + 5) =
A. 8x^2 + x +4
B. 8x^2+x+14
c. 7x^2+x+4
D. 7x^2+x+14

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
