6x^{2}+11x-10=\left(6x-1\right)\left(x+4\right)
Use the distributive property to multiply 3x-2 by 2x+5 and combine like terms.
6x^{2}+11x-10=6x^{2}+23x-4
Use the distributive property to multiply 6x-1 by x+4 and combine like terms.
6x^{2}+11x-10-6x^{2}=23x-4
Subtract 6x^{2} from both sides.
11x-10=23x-4
Combine 6x^{2} and -6x^{2} to get 0.
11x-10-23x=-4
Subtract 23x from both sides.
-12x-10=-4
Combine 11x and -23x to get -12x.
-12x=-4+10
Add 10 to both sides.
-12x=6
Add -4 and 10 to get 6.
x=\frac{6}{-12}
Divide both sides by -12.
x=-\frac{1}{2}
Reduce the fraction \frac{6}{-12} to lowest terms by extracting and canceling out 6.
