X squared + 7X + 12?
7x-x2 = x(7-x)
x2+7x x(x+7)
13X squared + 7X + 12
Factorise it: (x + 5)(3x - 8)
x^2+7x-30 = (x-3)(x+10)
(x + 11)(x - 4)
7x2+49x-42 = 7(x2+7x-6)
if its x(squared) its 7x(cubed) if its 2xX its 14x(squared)
It is: x(x-3) factorized
3(6x2-7x-24) by dividing all the terms by 3
x(x - 7)
