Question

Factorise it.
${ab}^{2} - {bc}^{2} - ab + {c}^{2}$

Answer 1

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

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

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

Answer 2

$Heya$‼


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



$Rearranging\:the\:term$:-

$=ab^2-ab-bc^2+c^2$

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

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



$Answer:- (ab-c^2)(b-1)$
