g(x) + f(x) = 2x² +7x -5 -8x² -3x +5
= -6x² +4x

Using addition of two polynomials, f(x) + g(x) =  2x² +4x - 64

What is polynomials?

Polynomials are "algebraic expressions that may comprise of exponents which are added, subtracted and multiplied".

According to the question,

f(x) = 2x² + 7x - 5

g(x) = -8² - 3x + 5

f(x) + g(x) = 2x² +4x - 64.
