Answer 2

Answer:

$\huge\mathfrak\orange{Answer}$

$= (b - 5)^{2} - (5b - 25) - 24$

$= (b - 5)^{2} - 5(b - 5) - 24$

$\red {let \: b - 5 = k}$

$= (b - 5 )^{2} - 5(b - 5) - 24$

$= {k}^{2} - 5k - 24$

$= {k}^{2} - 8k + 3k - 24$

$= k(k - 8) + 3(k - 8)$

$= (k - 8) \: \: \: \: \: \: (k + 3)$

$= (b - 5 - 8) \: \: \: (b - 5 + 3) \:( \red{repalce \: k = b - 5})$

$= (b - 13) \: \: \: \: (b - 2)$
