Fill in the second blank by multiplying the number outside the parenthesis and the number in the first blank in this case 2 9 is 18.
Where r and s are constants. Divide both sides of the equation by 5 to have 1 as the coefficient of the first term. Write the quadratic in the correct form since the leading coefficient is not a 1 you must factor the 2 out of the first two terms. The following are the general steps involved in solving quadratic equations using completing the square method.
