f%28x%29+=+-5x+-+3+ and g%28x%29+=+x%5E2+%2B+10x

(f o g)(x) means f[ g(x)] which means to take the g(x) formula and substitute it in the f(x) formula in place of the x.

f%28x%29+=+-5x+-3+
f%28+g%28x%29%29+=+-5%28x%5E2+%2B+10x%29+-+3

Multiplying it out you get:
f%28+g%28x%29%29+=+-5x%5E2+-+50x+-+3
