Answer 2

Answer:

$\sf\ x\implies: 12 \: and \: - 13$

Step-by-step explanation:

$\bf\huge\ {x}^{2} + x - 156 = 0 \\ \\ \sf\ \implies: {x}^{2} + (13x - 12x) - 156 = 0 \\ \\ \sf\ \implies: {x}^{2} + 13x - 12x - 156 = 0 \\ \\ \sf\ \implies: x(x + 13) - 12(x + 13) = 0 \\ \\ \sf\ \implies: (x - 12)(x + 13) = 0 \\ \\ \bf\ x - 12 = 0 \\ \sf\boxed{ \implies: x = 12} \\ \\ \bf\ x + 13 = 0 \\ \sf\boxed{ \implies: x = - 13}$
