Question 87551: Hello im having problems soving these 2 problems its asking me to solve.
let h(x)=4x-x^2. Find such that h(a)= -32
the other problem im having trouble with it
f(x)= 2x/5x^2-20
thanks for your help

You can put this solution on YOUR website!
let h(x)=4x-x^2. Find such that h(a)= -32
H(a) = 4a-a^2=-32
a^2-4a-32=0
(a-8)(a+4)=0
a = 8 or a = -4

the other problem im having trouble with it
f(x)= 2x/5x^2-20
