x^2 - x - 156 =0
x^2 -13x+12x -156 =0
x(x-13)+12(x-13)=0
(x-13)(x+12)=0
x=13 x=-12
x^2 -13x+12x -156 =0
x(x-13)+12(x-13)=0
(x-13)(x+12)=0
x=13 x=-12

Hey mate thank for the question
Hope it helps
=x2-x-156
=x2-(13-12)x-156
=x2-13x+12x-156
=x(x-13)+12(x-13)
=(x+12)(x-13)
x+12=-12. (not possible)
=x-13
=13 answer
