Question

factorise :- x-1-(x-1)2+ax-a​

Answer 1

$\huge \mathfrak \red{answer}$

$\sf\underline \pink{ \implies \: (x - 1)(2 - x + a)}$

$\huge \sf \underline \blue{Question}$

$\rm{x - 1(x - 1) {}^{2} + ax - a}$

__________________________________________________

$\sf \underline \green{step \: by \: step \: explanation }$

$\tt \orange{ \implies \: x - 1( \times - 1) {}^{2} + ax - a}$

$\tt \purple{ \implies \: = (x - 1) - (x - 1) {}^{2} + a(x - 1)}$

$\tt \red{ \implies \: = (x - 1)(1 - (x - 1) + a)}$

$\tt \blue{ \implies = \: (x - 1)(1 - x + 1 + a)}$

$\tt \pink{ \implies \: = (x - 1)(2 - x + a)}$
