Question

pleaee factorise it x²+x-12

Answer 1

x²+(4-3)x-12,

x²+4x-3x-12,

x(x+4)-3(x+4),

(x+4)(x-3)

Answer 2

$\huge {Hello \: Friends}$

$\underline\bold{Given}$

$\bf{x {}^{2} + x - 12} = 0$

$\underline\bold{solution}$

$\bold{ = > x {}^{2} + x - 12} = 0$
$\bf{ = > x {}^{2} + 4x - 3x - 12} = 0$
$\bold{ = > x(x + 4) - 3(x + 4)} = 0$
$\bf{ = > (x + 4) \: \: (x - 3)} = 0$

$\pink{When....}$

$\bf{x + 4 = 0}$
$\boxed{x \: = - 4}$

$\pink{When........}$

$\bf{x - 3 = 0}$

$\boxed{x = \: 3 }$
