Simplify (a-2) to the power of 3 for a a-5

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

What is the solution for the following system of equations? use any method to solve. 2x + 8y = 4 x = -3y + 5 question 4 options: x = 14, y= -3 x = 2, y = -3 x = -3, y = -3 x = 12, y = 5

Polynomials plz quick 1: subtract and simplify (–y^2 – 4y – 8) – (–4y^2 – 6y + 3)
