1) make coefficient of x2 be 1
2) shift constant term on right hand side
3) add half square of coefficient of x on both sides
4) calculate only RHS & on LHS use identity

For example take an equation
ax2+bx-c=0
step 1: Divide each side by 'a'.
step 2:Rearrange the equation so that constant term c/a is on the right side. (RHS).
step 3: Add [1/2(b/a)]2 to both sides to make LHS,a perfect square.
step 4: Write the LHS as a square and simplify the RHS.
step 5: Solve it
