Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Factorise by grouping method.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

$ab - 2b + {a}^{2} - 2a$

$=b(a - 2) + a(a - 2)$

$= (a + b)(a - 2)$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $(a + b)(a - 2)$

Answer 2

$\bf\large\blue{Question\::-}$

• Factorise it by grouping method :-
• $ab - 2b + a {}^{2} - 2a$

$\bf\large\blue{Solution\::-}$

$ab - 2b + a {}^{2} - 2a$

$= b(a - 2) + a(a - 2)$

$= (b + a)(a - 2)$

$\bf\large\blue{Answer\::-}$

• After factorising we get, $= (b + a)(a - 2)$
