x(x-6) = x^2 - 6x
4(x+6) = 4x + 24
First we need to eliminate the bracket by multiplying the numbers and variables from outside the bracket with the inside, we weill get :
X^2 - 6x = 4x + 24
(subtract 4x and 24 from both sides)
x^2 - 10x - 24 = 0
(x+2) (x-12) = 0
x+2 = 0 x-12 = 0
The value of X would be :
x = -2 x = 12
