-2x+1=4
Square both sides of the equation.
-2x+1-1=4-1
Subtract 1 from both sides of the equation.
-2x=4-1
Subtracting 1 from itself leaves 0.
-2x=3
Subtract 1 from 4.
\frac{-2x}{-2}=\frac{3}{-2}
Divide both sides by -2.
x=\frac{3}{-2}
Dividing by -2 undoes the multiplication by -2.
x=-\frac{3}{2}
Divide 3 by -2.
