Question

factorise the given algebriac expression by regrouping the terms: ab^2 - bc^2 - ab + c^2​

Answer 1

$\huge\underline\frak\orange{Solution}$

${ab^2-bc^2-ab+c^2}$

${ab^2-ab-bc^2+c^2}$

${ab(b-1)-c^2(b-1)}$

${(b-1)(ab-c^2)}$

Answer 2

Solution :-

ab²-bc²-ab+c²

ab²-ab-bc+c²

ab(b-1)-c²(b-1)

(b-1)(ab-c²)
