Factorization Question

Question

I need help factoring this problem: anything is appreciated. I have attempted this problem but I haven't been able to solve it so...here it is:

$$\frac{a^2 - ab + ab^2}{a^2 - b^2 + ab^2 +b^3}$$

Thanks

Answer 1

the denominator is given by $$a(a-b+b^2)$$ and the denominator $$a^2-b^2+b^2(a+b)=(a-b)(a+b)+b^2(a+b)$$ does this help you? and the fraction is given by $$\frac{a(a-b+b^2)}{(a+b)(a-b+b^2)}$$
