Answer:
f(g(-4)) = 13.
g(f(-4)) = -3.
Step-by-step explanation:
g(-4) = (-4)^2 + 3(-4) - 1
= 3.
so f(g(-4))
= f(3)
= 2(3) + 7
= 13.
f(-4) = 2(-4) + 7
= -1.
so g (f(-4))
= g(-1)
= (-1)^2 - 3 - 1
= -3.
First we see that we can factor out a 5 from everybody
5(-a^2+2ab^2-4+5ba^3)
trial and eror and experience
order in poawer order
5(5a^3b-a^2+2ab^2-4)
5(a^2(5ab-1)+2(ab^2-2))
dunno how to go on further
