\left(2x+3\right)\left(5x+2\right)+\left(2x^{2}-8\right)x=\left(2x^{2}-8\right)\left(x+4\right)+\left(x+2\right)\left(2x+3\right)
Variable x cannot be equal to any of the values -2,-\frac{3}{2},2 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-2\right)\left(x+2\right)\left(2x+3\right), the least common multiple of 2\left(x^{2}-4\right),2x+3,2\left(x-2\right).
10x^{2}+19x+6+\left(2x^{2}-8\right)x=\left(2x^{2}-8\right)\left(x+4\right)+\left(x+2\right)\left(2x+3\right)
Use the distributive property to multiply 2x+3 by 5x+2 and combine like terms.
10x^{2}+19x+6+2x^{3}-8x=\left(2x^{2}-8\right)\left(x+4\right)+\left(x+2\right)\left(2x+3\right)
Use the distributive property to multiply 2x^{2}-8 by x.
10x^{2}+11x+6+2x^{3}=\left(2x^{2}-8\right)\left(x+4\right)+\left(x+2\right)\left(2x+3\right)
Combine 19x and -8x to get 11x.
10x^{2}+11x+6+2x^{3}=2x^{3}+8x^{2}-8x-32+\left(x+2\right)\left(2x+3\right)
Use the distributive property to multiply 2x^{2}-8 by x+4.
10x^{2}+11x+6+2x^{3}=2x^{3}+8x^{2}-8x-32+2x^{2}+7x+6
Use the distributive property to multiply x+2 by 2x+3 and combine like terms.
10x^{2}+11x+6+2x^{3}=2x^{3}+10x^{2}-8x-32+7x+6
Combine 8x^{2} and 2x^{2} to get 10x^{2}.
10x^{2}+11x+6+2x^{3}=2x^{3}+10x^{2}-x-32+6
Combine -8x and 7x to get -x.
10x^{2}+11x+6+2x^{3}=2x^{3}+10x^{2}-x-26
Add -32 and 6 to get -26.
10x^{2}+11x+6+2x^{3}-2x^{3}=10x^{2}-x-26
Subtract 2x^{3} from both sides.
10x^{2}+11x+6=10x^{2}-x-26
Combine 2x^{3} and -2x^{3} to get 0.
10x^{2}+11x+6-10x^{2}=-x-26
Subtract 10x^{2} from both sides.
11x+6=-x-26
Combine 10x^{2} and -10x^{2} to get 0.
11x+6+x=-26
Add x to both sides.
12x+6=-26
Combine 11x and x to get 12x.
12x=-26-6
Subtract 6 from both sides.
12x=-32
Subtract 6 from -26 to get -32.
x=\frac{-32}{12}
Divide both sides by 12.
x=-\frac{8}{3}
Reduce the fraction \frac{-32}{12} to lowest terms by extracting and canceling out 4.
