\left(x-3\right)\left(x+1\right)=\left(x-2\right)\left(x+5\right)+\left(x-3\right)\left(x-2\right)
Variable x cannot be equal to any of the values 2,3 since division by zero is not defined. Multiply both sides of the equation by \left(x-3\right)\left(x-2\right), the least common multiple of x-2,x-3.
x^{2}-2x-3=\left(x-2\right)\left(x+5\right)+\left(x-3\right)\left(x-2\right)
Use the distributive property to multiply x-3 by x+1 and combine like terms.
x^{2}-2x-3=x^{2}+3x-10+\left(x-3\right)\left(x-2\right)
Use the distributive property to multiply x-2 by x+5 and combine like terms.
x^{2}-2x-3=x^{2}+3x-10+x^{2}-5x+6
Use the distributive property to multiply x-3 by x-2 and combine like terms.
x^{2}-2x-3=2x^{2}+3x-10-5x+6
Combine x^{2} and x^{2} to get 2x^{2}.
x^{2}-2x-3=2x^{2}-2x-10+6
Combine 3x and -5x to get -2x.
x^{2}-2x-3=2x^{2}-2x-4
Add -10 and 6 to get -4.
x^{2}-2x-3-2x^{2}=-2x-4
Subtract 2x^{2} from both sides.
-x^{2}-2x-3=-2x-4
Combine x^{2} and -2x^{2} to get -x^{2}.
-x^{2}-2x-3+2x=-4
Add 2x to both sides.
-x^{2}-3=-4
Combine -2x and 2x to get 0.
-x^{2}=-4+3
Add 3 to both sides.
-x^{2}=-1
Add -4 and 3 to get -1.
x^{2}=\frac{-1}{-1}
Divide both sides by -1.
x^{2}=1
Divide -1 by -1 to get 1.
x=1 x=-1
Take the square root of both sides of the equation.

x=\frac{0±\sqrt{0^{2}-4\left(-1\right)}}{2\left(-1\right)}
This equation is in standard form: ax^{2}+bx+c=0. Substitute -1 for a, 0 for b, and 1 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-1\right)}}{2\left(-1\right)}
Square 0.
x=\frac{0±\sqrt{4}}{2\left(-1\right)}
Multiply -4 times -1.
x=\frac{0±2}{2\left(-1\right)}
Take the square root of 4.
x=\frac{0±2}{-2}
Multiply 2 times -1.
x=-1
Now solve the equation x=\frac{0±2}{-2} when ± is plus. Divide 2 by -2.
x=1
Now solve the equation x=\frac{0±2}{-2} when ± is minus. Divide -2 by -2.
x=-1 x=1
The equation is now solved.
