\left(x+2\right)\left(x+1\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,x+2.
x^{2}+3x+2=\left(x-2\right)\left(x-1\right)
Use the distributive property to multiply x+2 by x+1 and combine like terms.
x^{2}+3x+2=x^{2}-3x+2
Use the distributive property to multiply x-2 by x-1 and combine like terms.
x^{2}+3x+2-x^{2}=-3x+2
Subtract x^{2} from both sides.
3x+2=-3x+2
Combine x^{2} and -x^{2} to get 0.
3x+2+3x=2
Add 3x to both sides.
6x+2=2
Combine 3x and 3x to get 6x.
6x=2-2
Subtract 2 from both sides.
6x=0
Subtract 2 from 2 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 6 is not equal to 0, x must be equal to 0.
