\left(3x-2\right)\left(4x+1\right)+6x\left(x+3\right)\left(-2\right)=0
Variable x cannot be equal to any of the values -3,0 since division by zero is not defined. Multiply both sides of the equation by 6x\left(x+3\right).
12x^{2}-5x-2+6x\left(x+3\right)\left(-2\right)=0
Use the distributive property to multiply 3x-2 by 4x+1 and combine like terms.
12x^{2}-5x-2-12x\left(x+3\right)=0
Multiply 6 and -2 to get -12.
12x^{2}-5x-2-12x^{2}-36x=0
Use the distributive property to multiply -12x by x+3.
-5x-2-36x=0
Combine 12x^{2} and -12x^{2} to get 0.
-41x-2=0
Combine -5x and -36x to get -41x.
-41x=2
Add 2 to both sides. Anything plus zero gives itself.
x=\frac{2}{-41}
Divide both sides by -41.
x=-\frac{2}{41}
Fraction \frac{2}{-41} can be rewritten as -\frac{2}{41} by extracting the negative sign.
