Given the functions f(x) = 3x2 – 5x + 2 and g(x) = –4x2 + 3, what is f(x) – g(x)?

Question

i need help on this pleaseeee

Answer 1

f(x) -g(x) = 7x^2 -5x -1

3x^2 -5x + 2 = f(x)

-4x^2 +3 = g(x)

7x^2 - 5x - 1

Just subtract like terms: subtracting a negative number is the same as changing its sign and adding

3x^2 - - 4x^2 = 3x^2 + 4x^2 = 7x^2

2-3 = -1
