Question

Let f(x)=2x^2+7x-5 and g(x)=-8^2-3x+5 what is g(x)+f(x)

Answer 1

2x^2 + 4x - 64

Explanation:

it is telling us to add the functions together so we use this equation:

2x^2 + 7x - 5 + (-8^2) - 3x + 5

after combining like terms we get

2x^2 + 4x -8^2

and then lastly we square the -8 and get

2x^2 + 4x - 64
