4x^{2}+12x+9+y\left(2x+3\right)-z=0
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(2x+3\right)^{2}.
4x^{2}+12x+9+2yx+3y-z=0
Use the distributive property to multiply y by 2x+3.
12x+9+2yx+3y-z=-4x^{2}
Subtract 4x^{2} from both sides. Anything subtracted from zero gives its negation.
9+2yx+3y-z=-4x^{2}-12x
Subtract 12x from both sides.
2yx+3y-z=-4x^{2}-12x-9
Subtract 9 from both sides.
2yx+3y=-4x^{2}-12x-9+z
Add z to both sides.
\left(2x+3\right)y=-4x^{2}-12x-9+z
Combine all terms containing y.
\left(2x+3\right)y=-4x^{2}-12x+z-9
The equation is in standard form.
\frac{\left(2x+3\right)y}{2x+3}=\frac{-\left(2x+3\right)^{2}+z}{2x+3}
Divide both sides by 2x+3.
y=\frac{-\left(2x+3\right)^{2}+z}{2x+3}
Dividing by 2x+3 undoes the multiplication by 2x+3.
y=\frac{-4x^{2}-12x+z-9}{2x+3}
Divide z-\left(2x+3\right)^{2} by 2x+3.
4x^{2}+12x+9+y\left(2x+3\right)-z=0
