10x^{2}-13x-3=\left(10x-9\right)\left(x+2\right)
Use the distributive property to multiply 5x+1 by 2x-3 and combine like terms.
10x^{2}-13x-3=10x^{2}+11x-18
Use the distributive property to multiply 10x-9 by x+2 and combine like terms.
10x^{2}-13x-3-10x^{2}=11x-18
Subtract 10x^{2} from both sides.
-13x-3=11x-18
Combine 10x^{2} and -10x^{2} to get 0.
-13x-3-11x=-18
Subtract 11x from both sides.
-24x-3=-18
Combine -13x and -11x to get -24x.
-24x=-18+3
Add 3 to both sides.
-24x=-15
Add -18 and 3 to get -15.
x=\frac{-15}{-24}
Divide both sides by -24.
x=\frac{5}{8}
Reduce the fraction \frac{-15}{-24} to lowest terms by extracting and canceling out -3.
