\left(2x+3\right)\times 2+\left(2x-3\right)\times 2x=\left(2x-3\right)\left(2x+3\right)
Variable x cannot be equal to any of the values -\frac{3}{2},\frac{3}{2} since division by zero is not defined. Multiply both sides of the equation by \left(2x-3\right)\left(2x+3\right), the least common multiple of 2x-3,2x+3.
4x+6+\left(2x-3\right)\times 2x=\left(2x-3\right)\left(2x+3\right)
Use the distributive property to multiply 2x+3 by 2.
4x+6+\left(4x-6\right)x=\left(2x-3\right)\left(2x+3\right)
Use the distributive property to multiply 2x-3 by 2.
4x+6+4x^{2}-6x=\left(2x-3\right)\left(2x+3\right)
Use the distributive property to multiply 4x-6 by x.
-2x+6+4x^{2}=\left(2x-3\right)\left(2x+3\right)
Combine 4x and -6x to get -2x.
-2x+6+4x^{2}=\left(2x\right)^{2}-9
Consider \left(2x-3\right)\left(2x+3\right). Multiplication can be transformed into difference of squares using the rule: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}. Square 3.
-2x+6+4x^{2}=2^{2}x^{2}-9
Expand \left(2x\right)^{2}.
-2x+6+4x^{2}=4x^{2}-9
Calculate 2 to the power of 2 and get 4.
-2x+6+4x^{2}-4x^{2}=-9
Subtract 4x^{2} from both sides.
-2x+6=-9
Combine 4x^{2} and -4x^{2} to get 0.
-2x=-9-6
Subtract 6 from both sides.
-2x=-15
Subtract 6 from -9 to get -15.
x=\frac{-15}{-2}
Divide both sides by -2.
x=\frac{15}{2}
Fraction \frac{-15}{-2} can be simplified to \frac{15}{2} by removing the negative sign from both the numerator and the denominator.
