Answer 1

Answer:

$\huge\mathfrak\colorbox{black}{Answer}$

$\sf{⇒ \: (x - 9)(x + 7)}$

Binomial multiplication: multiply (x-9) and (x+7).

$\sf{⇒ \: {x}^{2} + 7x - 9x - 63}$

$\sf{⇒ \: {x}^{2} - 2x - 63}$

$\sf{⇒ \: {x}^{2} - 9x + 7x - 63}$

Splitting the middle term by sum and product method.

$\sf{⇒ \: x(x - 9) + 7(x - 9)}$

$\sf{⇒ \: (x + 7)(x - 9)}$
