Question

$7x {}^{2} + 5x - 12$

Answer 1

$hey \: here \: is \: your \: answer \\ 7x {}^{2} + 5x - 12 \\ 7x {}^{2} + 12x - 7x - 12 \\ x(7x + 12) - 1(7x + 12) \\ (x - 1)(7x + 12) \\ l \: hope \: it \: wi ll \: help \: you$

Answer 2

$7 {x}^{2} + 5x - 12 = 0 \\ 7 {x}^{2} +(12x - 7x) - 12 = 0 \\ 7 {x }^{2} + 12x - 7x - 12 = 0 \\ x(7x + 12) - 1(7x + 12) = 0 \\ (7x + 12)(x - 1) = 0 \\ x = \frac{ - 12}{7} and \: x = 1$
hope this will help you
