x^2+b/ax+(b/(2a))^2=-(4ac)/(4a^2) +(b^2)/(4a^2) Find a common denominator on the right side of the equation

x^2+b/ax+(b/(2a))^2=(b^2-(4ac))/( 4a^2) Add the fractions together on the right side of the equation

(x+b/(2a))^2=(b^2-(4ac))/(4a^2) Rewrite the perfect square trinomial on the left side of the equation

? Simply the right side of the equation

x+b/(2a)= ± sqrt(b^2-(4ac)/(4a^2))
