Question

(c)
(a* -b") = (a-ab)​

Answer 1

Answer:

$\dfrac{(a + b)(a^2 + b^2)}{a}$

Step-by-step explanation:

$(a^4 - b^4) \div (a^2 - ab)$

$= \dfrac{a^4 - b^4}{a^2 - ab}$

$= \dfrac{(a^2)^2 - (b^2)^2}{a(a - b)}$

$= \dfrac{(a^2 - b^2)(a^2 + b^2)}{a(a - b)}$

$= \dfrac{(a - b)(a + b)(a^2 + b^2)}{a(a - b)}$

$= \dfrac{(a + b)(a^2 + b^2)}{a}$
