x=-2,12x=2,12

Explanation:

The first step is cross multiple:

x(x-2)=8(x-3)x(x2)=8(x3)

Distribute:

x^2-2x=8x-24x22x=8x24

Then subtract -8x8x from both side and add 2424 to both sides.

x^2-2x-8x+24=0x22x8x+24=0

Simplify:

x^2-10x+24x210x+24

Factor and set the factors equal to zero:

(x-12)(x-2)=0(x12)(x2)=0

Solve and you get:

x=-2,12x=2,12
