\left(2x-2\right)\left(x-1\right)+\left(4x+10\right)\left(2x+1\right)=5\left(x-1\right)\left(2x+5\right)
Variable x cannot be equal to any of the values -\frac{5}{2},1 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-1\right)\left(2x+5\right), the least common multiple of 2x+5,x-1,2.
2x^{2}-4x+2+\left(4x+10\right)\left(2x+1\right)=5\left(x-1\right)\left(2x+5\right)
Use the distributive property to multiply 2x-2 by x-1 and combine like terms.
2x^{2}-4x+2+8x^{2}+24x+10=5\left(x-1\right)\left(2x+5\right)
Use the distributive property to multiply 4x+10 by 2x+1 and combine like terms.
10x^{2}-4x+2+24x+10=5\left(x-1\right)\left(2x+5\right)
Combine 2x^{2} and 8x^{2} to get 10x^{2}.
10x^{2}+20x+2+10=5\left(x-1\right)\left(2x+5\right)
Combine -4x and 24x to get 20x.
10x^{2}+20x+12=5\left(x-1\right)\left(2x+5\right)
Add 2 and 10 to get 12.
10x^{2}+20x+12=\left(5x-5\right)\left(2x+5\right)
Use the distributive property to multiply 5 by x-1.
10x^{2}+20x+12=10x^{2}+15x-25
Use the distributive property to multiply 5x-5 by 2x+5 and combine like terms.
10x^{2}+20x+12-10x^{2}=15x-25
Subtract 10x^{2} from both sides.
20x+12=15x-25
Combine 10x^{2} and -10x^{2} to get 0.
20x+12-15x=-25
Subtract 15x from both sides.
5x+12=-25
Combine 20x and -15x to get 5x.
5x=-25-12
Subtract 12 from both sides.
5x=-37
Subtract 12 from -25 to get -37.
x=\frac{-37}{5}
Divide both sides by 5.
x=-\frac{37}{5}
Fraction \frac{-37}{5} can be rewritten as -\frac{37}{5} by extracting the negative sign.
