Question

Let f(x) = 3x^2 + x − 3 and g(x) = x^2 − 5x + 1. Find f(x) − g(x).

Answer 1

they want you to subtract the two formulas
I would do it term by term. for example, any idea what is
3x^2 - x^2 ?

i.e. what is 3 "x squared"s take away 1 "x squared" ?

Answer 2

2x ?

Answer 3

2 x^2 (you have two of "x squared" not just x)

Answer 4

now do x - -5x (remember minus a minus turns into a +)

Answer 5

ohhh okay. i didnt read it right
