Answer 2

Answer:

$\huge \underline{ Answer✿°᭄}$

$let \: a + b = x \\ \\⇒ \: ( a+ b) ^{2} = {x}^{2} \\ \\ ⇒ \: 8 + 6(a + b) - 5 {( a+b) }^{2} \\ \\ ⇒ \: 8 + 6x - 5 {x}^{2} \\ \\ ⇒ \: 8 + 10x - 4x - 5 {x}^{2} \\ \\ ⇒ \: 2(4 + 5x) - x(4 + 5x) \\ \\ ⇒ \: (4 + 5x)(2 - x) \\ \\ ⇒ \: [4 + 5(a + b)][2 - ( a+b )] \\ \\ (substituting \: the \: value \: x) \\ \\ ⇒ \: [4 + 5(a + b)][2 - ( a+b )]$
