Question

Find the sum of these polynomials.

(x6 + x + 9) + (7x6 + 5) =
A. 7x12 + x + 14
B.8x6 + x + 14
C.7x6 + x + 14
D.8x12 + x + 14

Answer 1

Hello @destinib0123 and Welcome to OpenStudy! :)

For your question, since the sign between your two sets of parenthesis is an addition sign, we can ignore the parenthesis and have
\(x^6 + x + 9 + 7x^6 + 5\)

Answer 2

From there we can "add like terms"
which is when we only add the numbers that have the same variable powers

so like
\(x^6 + 7x^6 = 8x^6 \)

do you understand that so far? :)

I noticed that you have gone offline @destinib0123

Adding the like terms should get you to your answer ^_^
