Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. 2a2 − 30a + 108 = 0

the quadratic formula is

- b + - \sqrt{ {b}^(2) - 4ac } / 2a
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

Two real solutions:


a =(15+√9)/2=(15+3)/2= 9.000


or:


a =(15-√9)/2=(15-3)/2= 6.000



Two solutions were found :

a = 9

a = 6
