Question

simplify the following:‐ (a‐b) (a²+b²+ab)‐(a+b) (a²+b²‐ab)?​

Answer 1

Answer:

Step-by-step explanation:

(b - a)/(a² - b²) = (b - a)/[(a - b)(a + b)]

= [(-1)(a - b)]/[(a - b)(a + b)]

By the Associative Property of Multiplication, i.e, for any numbers a, b, and c, a(bc) = (ab)c, we have:

= [(a - b)/(a - b)][-1/(a + b)]

= [1][-1/(a + b)]

= -1/(a + b) is (b - a)/(a² - b²) simplified
