The steps
Multiply all terms by (x-3)(x+3) and cancel:
x(x+3)+2x(x−3)=18
3x2−3x=18(Simplify both sides of the equation)
3x2−3x−18=18−18(Subtract 18 from both sides)
3x2−3x−18=0
3(x+2)(x−3)=0(Factor left side of equation)
x+2=0 or x−3=0(Set factors equal to 0)
x=−2 or x=3
Check answers. (Plug them in to make sure they work.)
x=−2 (Works in original equation)
x=3 (Doesn't work in original equation)
