Best ResponseYou've already chosen the best response.0completing the square means you need the equation to be in the form of c^2+/ d^2 Algorithm!! Step 1 Bring all the variable terms to one side and the constant terms to the ryt side. Step 2 add half of the coefficient of the variable of first degree on both sides. Step 3 Your left hand side equation/sum will be of the form (a+/b)^2 and right hand side will be a constant numerical term. Step 4 Bring in the constant term back on the left side changing the side,i.e, adding or subtracting the constant term on both side as required. Step 5 Find the square root of the constant term and write the constant term as the square of it. Step 6 Consider the (a+/b)^2 form as c^2 and the constant term d^2. Put it in the equation I wrote first and VIOLA!!!
