2\left(x-p\right)x=3\left(6p-x\right)
Multiply both sides of the equation by x.
\left(2x-2p\right)x=3\left(6p-x\right)
Use the distributive property to multiply 2 by x-p.
2x^{2}-2px=3\left(6p-x\right)
Use the distributive property to multiply 2x-2p by x.
2x^{2}-2px=18p-3x
Use the distributive property to multiply 3 by 6p-x.
2x^{2}-2px-18p=-3x
Subtract 18p from both sides.
-2px-18p=-3x-2x^{2}
Subtract 2x^{2} from both sides.
\left(-2x-18\right)p=-3x-2x^{2}
Combine all terms containing p.
\left(-2x-18\right)p=-2x^{2}-3x
The equation is in standard form.
\frac{\left(-2x-18\right)p}{-2x-18}=-\frac{x\left(2x+3\right)}{-2x-18}
Divide both sides by -2x-18.
p=-\frac{x\left(2x+3\right)}{-2x-18}
Dividing by -2x-18 undoes the multiplication by -2x-18.
p=\frac{x\left(2x+3\right)}{2\left(x+9\right)}
Divide -x\left(3+2x\right) by -2x-18.
