Question

Ab²-bc² -ab+ c² do this question for factorise method

Answer 1

=ab(b-1)-c^2(b-1)
=(ab-c^2)(b-1)

Answer 2

$\huge{\underline{\tt{QUESTION:-}}} \\ \\ Factorise \: the following \: - \\ \\ a {b}^{2} - b {c}^{2} - ab + {c}^{2} \\ \\ \huge{\underline{\tt{ANSWER:-}}} \\ \\ a {b}^{2} - b {c}^{2} - ab + {c}^{2} \\ = b(ab - {c}^{2} ) - ab + {c}^{2} \\ = b(ab - {c}^{2} ) - 1(ab - {c}^{2} ) \\ = (ab - {c}^{2} )(b - 1)$
