Question

x² -4x+4 factorise it​

Answer 1

Step-by-step explanation:

» x² - 4x + 4

» x² - 2x - 2x + 4

» x(x - 2 ) - 2 ( x - 2 )

» (x - 2 ) (x - 2)

Answer 2

$\Huge\tt\orange{an{\mathcal{S}}wer:}$

${ }$

$\bf{{\underline{To~factorise}}:}$

$\tt{~~~~~~~~ x^{2}-4x+4}$

$\color{navy}{\boxed{\sf S=-4~~,~~P=4~~~~~~(-2~,~-2)}}$

$\tt\longmapsto{(x^{2}-2x)+(-2x+4)}$

$\tt\longmapsto{[x(x-2)~]+[-2(x-2)~]}$

$\tt\longmapsto{(x-2)(x-2)}$

$\bf\therefore{{\underline{Required~answer}}:}$

$\sf{~~~~~~~~The~factors~are:~~{\orange{\underline{\boxed{\bf x-2}}}}~~and~~{\orange{\underline{\boxed{\bf x-2}}}}}$
