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