Question

Let f(x) = 3x2 + x − 3 and g(x) = x2 − 5x + 1. Find f(x) − g(x).

2x2 − 4x − 2
2x2 − 4x − 4
2x2 + 6x − 2
2x2 + 6x − 4

Answer 1

Well if f(x) is \(3x^2 + x − 3\) and g(x) is \(x^2 − 5x + 1\)

\[f(x) − g(x) \\ \\ =(3x^2 + x − 3) - (x^2 − 5x + 1)\]

Answer 2

Simplify it and you should get your answer.
