the quadratic formula is [tex] - b + - \sqrt{ {b}^{2} - 4ac } \div 2a[/tex] A = 2 B = -30 C = 108 plug in the values for the equation and you'll get what the factors are
-(-30)+√(-30)²-4(2)(108))/2(2)
and
-(-30)-√(-30)²-4(2)(108))/2(2) This will give you your A values and just round the answers from both of the above equations
