a= b= c=

Put in numbers for $$ax^2+bx=c$$ and we will complete the square for you. Inputs must be integers or fractions. No other math expressions can be input for the coefficients. Also, decimal fractions like 0.5, must be preceeded by the 0. The values that are used for a, b, and c are echoed at the page bottom.
