Answer 1

Answer:

(a-18)(2a+1)

Answer 2

$</p><p>\small {\blue{\fcolorbox{red}{orange}{\boxed{\orange{\bf{\underbrace{\overbrace{\fcolorbox{blue}{black} { \underline{ \pink{ question}}}}}}}}}}}$

$\implies \: 2 {a}^{2} - 35a - 18$

$</p><p>\small {\blue{\fcolorbox{red}{orange}{\boxed{\orange{\bf{\underbrace{\overbrace{\fcolorbox{blue}{black} { \underline{ \pink{ Solution}}}}}}}}}}}$

$\implies \: 2 {a}^{2} - (36 - 1)a - 18 \\ \\ \implies \: 2 {a}^{2} - 36a + a - 18 \\ \\ \implies \: 2a(a - 18) + 1(a - 18) \\ \\ \implies \red {(a - 18)(2a + 1)} \\ \\ \bf \: this \: is \: our \: required \: \\ \bf \: factorisation \: . \:$
