# Solve for b y=3+bx-2x^2 y=3+bx-2×2
Rewrite the equation as 3+bx-2×2=y.
3+bx-2×2=y
Move all terms not containing b to the right side of the equation.
Subtract 3 from both sides of the equation.
bx-2×2=y-3
Add 2×2 to both sides of the equation.
bx=y-3+2×2
bx=y-3+2×2
Divide each term by x and simplify.
Divide each term in bx=y-3+2×2 by x.
