Question

Find the sum of these polynomials.

Answer 1

x² – x + 8+ 10x² + 7 = 11x²-x+15
answer A

Answer 2

Answer:

$11x^2-x+15$

A is the correct option.

Step-by-step explanation:

We have to find the sum of the polynomials $(x^2-x+8)+(10x^2+7)$

On removing the parentheses, we get

$x^2-x+8+10x^2+7$

Group the like terms

$x^2+10x^2-x+8+7$

Combine the like terms

$11x^2-x+15$

Therefore, the sum of the polynomials is $11x^2-x+15$

A is the correct option.
