Answer 1

QUESTION : ↓

3x-x square - 4 factorise

ANSWER : ↓

$3 {x}^{2} - x - 4 \\ 3{x}^{2} - (4x - 3x) - 4 \\ 3 {x}^{2} - 4x + 3x - 4 \\ x(3x - 4) + 1(3x - 4) \\ (x + 1)(3x - 4)$

Taking 0 both sides

$x + 1 = 0 \: \: \: \: \: \: 3x - 4 = 0 \\ \\ { \fbox{x = 1}} \: \: \: \: \: { \fbox{x = 4 \3}}$
