If f(x) = 2x2 - 5
and
g(x) = 5x +7
Find
g(f(x)) = [? ]x2 +

Help pls

10x^2 -18

Step-by-step explanations

since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
