Question

need help in steps.
underline each term in the following polynomials and write the number , variable, or expression that each term has in common in the space provided.
5x(3x+1)+7(3x+1)

_____________

Answer 1

Let's simplify step-by-step.
5x(3x+1)+7(3x+1)
Distribute:
=(5x)(3x)+(5x)(1)+(7)(3x)+(7)(1)
=15x2+5x+21x+7
Combine Like Terms:
=15x2+5x+21x+7
=(15x2)+(5x+21x)+(7)
=15x2+26x+7
Answer:
=15x2+26x+7

Answer 2

i dont need to solve it.
it says.
