Answer 2

$\huge { \mathbb{ \sf{ \underbrace{ \underline{answer}}}}}$

$x {}^{2} - 22x + 120 \\ \implies \: p + q = - 22 \:and \: pq = 120 \\ \implies( - 12) + ( - 10) = - 22 \\ \implies( - 12) \: \times ( - 10) \: = 120 \\ \implies \: x { }^{2} - 22x + 12 = x {}^{2} - 12x \\ - 10x + 120 \\ \implies \: (x {}^{2} - 12) + ( - 10x + 120) \\ \implies \: x(x - 12) - 10(x - 120) \\ \implies(x - 10)(x - 12)$
