Question

Some polynomial F(x,a) What is this polynomial?
After simplification
[f(x)-f(a)]/(x-a) = F(x,a)/[(2x^2+2)(2a^2+2)]

what is the polynomial of F(x,a)?

I got
a^2-x^2

which is wrong

Answer 1

Oh yeah the original function was
f(x)=1/
2x^2+2

Answer 2

\[\large \frac{(\frac{1}{ 2x^2+2}-\frac{1}{ 2a^2+2})}{x-a}\]Is this your ques?

Answer 3

I think so and then it gets simplified to F(x,a)/[(2x^2+2)(2a^2+2)]
is the polynomial the stuff on top?

Answer 4

WHAT DOES THIS MEAN?
