4+\left(x+2\right)\left(x+3\right)=\left(x-2\right)\left(x-1\right)
Variable x cannot be equal to any of the values -2,2 since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(x+2\right), the least common multiple of x^{2}-4,x-2,x+2.
4+x^{2}+5x+6=\left(x-2\right)\left(x-1\right)
Use the distributive property to multiply x+2 by x+3 and combine like terms.
10+x^{2}+5x=\left(x-2\right)\left(x-1\right)
Add 4 and 6 to get 10.
10+x^{2}+5x=x^{2}-3x+2
Use the distributive property to multiply x-2 by x-1 and combine like terms.
10+x^{2}+5x-x^{2}=-3x+2
Subtract x^{2} from both sides.
10+5x=-3x+2
Combine x^{2} and -x^{2} to get 0.
10+5x+3x=2
Add 3x to both sides.
10+8x=2
Combine 5x and 3x to get 8x.
8x=2-10
Subtract 10 from both sides.
8x=-8
Subtract 10 from 2 to get -8.
x=\frac{-8}{8}
Divide both sides by 8.
x=-1
Divide -8 by 8 to get -1.
