Set up Quadratix Eq'n

x^(2( + 66x + 60 = 0

Complete the

Square

x^(2) + 66x = -60

(x - 33)^(2) - )33)^(2) = -60

(x - 33)^(2) = -60 + 33^(2)

(x - 33)^(2) = -60 + 1089

( x - 33)^*2) = 1029

Square root both sides

x - 33 = sqrt(1029( = +/- 32.078....

x = -33 +/- 32.078.....

x = -0.92197.... & -65.078.... are the two numbers.
