Question

please help 100 points!!! will give crown to best answer if f(x) = 3x^2 -2x + 4 and g (x) = 5x ^2 + 6x -8 find (f-g) (x)

Answer 1

(f-g)(x) will be 3x^2 -2x+4 -(5x^2+6×-8)
distribute the -sign, gives us
3x^2-2x+4-5x^2-6x+8,
now combine like terms and should get,
-2x^2-8x+12,
final answer,
(f-g)(x)= -2x^2-8x+1×,
hope it helped,
good luck

Answer 2

F(x) - g(x). We will subtract the terms and negate everything on the g(x) side as it is subtraction. We get 3x^2 - 2x +4 -5x^2 -6x +8 which equals -2x^2 +6x +12
