\left(4x+3\right)\left(6x^{2}+13x-4\right)=\left(2x+5\right)\left(12x^{2}+5x-2\right)
Variable x cannot be equal to any of the values -\frac{5}{2},-\frac{3}{4} since division by zero is not defined. Multiply both sides of the equation by \left(2x+5\right)\left(4x+3\right), the least common multiple of 2x+5,4x+3.
24x^{3}+70x^{2}+23x-12=\left(2x+5\right)\left(12x^{2}+5x-2\right)
Use the distributive property to multiply 4x+3 by 6x^{2}+13x-4 and combine like terms.
24x^{3}+70x^{2}+23x-12=24x^{3}+70x^{2}+21x-10
Use the distributive property to multiply 2x+5 by 12x^{2}+5x-2 and combine like terms.
24x^{3}+70x^{2}+23x-12-24x^{3}=70x^{2}+21x-10
Subtract 24x^{3} from both sides.
70x^{2}+23x-12=70x^{2}+21x-10
Combine 24x^{3} and -24x^{3} to get 0.
70x^{2}+23x-12-70x^{2}=21x-10
Subtract 70x^{2} from both sides.
23x-12=21x-10
Combine 70x^{2} and -70x^{2} to get 0.
23x-12-21x=-10
Subtract 21x from both sides.
2x-12=-10
Combine 23x and -21x to get 2x.
2x=-10+12
Add 12 to both sides.
2x=2
Add -10 and 12 to get 2.
x=\frac{2}{2}
Divide both sides by 2.
x=1
Divide 2 by 2 to get 1.
