Please help me to complete my maths home work.

Answer 1

$a { }^{2} + ab - 2b - 2a$
IT is a quadratic equation.

so

Solution .
$a(a + b) - 2(a + b)$
=>
$(a - 2)(a + b)$

Answer 2

$\underline \bold {Solution:-}$

$ab - 2b + {a}^{2} - 2a \\ \\ = {a}^{2} + ab - 2b - 2a \\ \\ = a(a + b) - 2(b + a) \\ \\ = a(a + b) - 2(a + b) \\ \\ = (a - 2)(a + b)$
