\left(x-2\right)\left(2x+3\right)+\left(x+2\right)\left(3x-2\right)=\left(x+3\right)\left(5x-2\right)
Variable x cannot be equal to any of the values -3,-2,2 since division by zero is not defined. Multiply both sides of the equation by \left(x-2\right)\left(x+2\right)\left(x+3\right), the least common multiple of x^{2}+5x+6,x^{2}+x-6,x^{2}-4.
2x^{2}-x-6+\left(x+2\right)\left(3x-2\right)=\left(x+3\right)\left(5x-2\right)
Use the distributive property to multiply x-2 by 2x+3 and combine like terms.
2x^{2}-x-6+3x^{2}+4x-4=\left(x+3\right)\left(5x-2\right)
Use the distributive property to multiply x+2 by 3x-2 and combine like terms.
5x^{2}-x-6+4x-4=\left(x+3\right)\left(5x-2\right)
Combine 2x^{2} and 3x^{2} to get 5x^{2}.
5x^{2}+3x-6-4=\left(x+3\right)\left(5x-2\right)
Combine -x and 4x to get 3x.
5x^{2}+3x-10=\left(x+3\right)\left(5x-2\right)
Subtract 4 from -6 to get -10.
5x^{2}+3x-10=5x^{2}+13x-6
Use the distributive property to multiply x+3 by 5x-2 and combine like terms.
5x^{2}+3x-10-5x^{2}=13x-6
Subtract 5x^{2} from both sides.
3x-10=13x-6
Combine 5x^{2} and -5x^{2} to get 0.
3x-10-13x=-6
Subtract 13x from both sides.
-10x-10=-6
Combine 3x and -13x to get -10x.
-10x=-6+10
Add 10 to both sides.
-10x=4
Add -6 and 10 to get 4.
x=\frac{4}{-10}
Divide both sides by -10.
x=-\frac{2}{5}
Reduce the fraction \frac{4}{-10} to lowest terms by extracting and canceling out 2.
