Question

Solve x2 + 4x — 12 = 0 by using middle term splitting method?​

Answer 1

Step-by-step explanation:

$x {}^{2} + 4x - 12 = 0 \\ or \: \: x {}^{2} + 6x - 2x - 12 = 0 \\ or \: \: x(x + 6) - 2(x + 6) = 0 \\ or \: \: (x + 6)(x - 2) = 0 \\ (x + 6) = 0 \\ or \: \: x = - 6 \\ (x - 2) = 0 \\ or \: \: x = 2 \\ hence \: \: x = - 6 \\ x = 2$
