Question

find the factors of x^2+x-12​

Answer 1

Step-by-step explanation:

x^2+x–12

=x^2 +4x-3x-12

=x(x+4)–3(x+4)

=(x+4)(x–3)

Answer 2

$\huge \sf {\purple{\underline {\pink {\underline { Answer᭄\ }}}}}$

x² + x - 12

Performing factorization ,

x² + 4x - 3x - 12 [ taking 4 & 3 as factors of 12 ]

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

x + 4 = 0 or x - 3 = 0

x = - 4 or x = 3
