Four steps to derive the quadratic formu...

Four steps to derive the quadratic formula are shown below .
(I) `x^(2)+(bx)/a=(-c)/a`
(II) `(x+b/(2a))^(2)=(b^(2)-4ac)/(4a^(2))`
(III) `x =pm sqrt((b^(2)-4ac)/(4a^(2)))-b/(2a)`
(IV) `x^(2)+(bx)/a +(b/(2a))^(2)=(-c)/a + (b/(2a))^(2)`
What is the correct order for these steps ?
