Question

F(x)=x^2+2x, then find fof(x)

Answer 1

Let x² +2x=0

Then x²= -2x

And hence x=root - 2x

Answer 2

Answer:

hey frnd here is your answer

Step-by-step explanation:

f(x)=x²+2x.

we have to find f(f(x)) so keep x=x²+2x in x²+2x.

x²+2x

(x²+2x)²+2(x²+2x)

x⁴+4x³+4x²+2x²+4

x⁴+4x³+6x²+4x.

So your final answer is x⁴+4x³+6x²+4x.

I hope u get your answer
