f(x) = -4x^2 + 9x + 3 = 0

a = -4, b = 9, c = 3

b^2 - 4ac = 9^2 - 4(-4)(3) = 129

x = (-9 + sqrt129)/-8 = (9 - sqrt 129)/8 = - 0.29

or x = (-9 - sqrt129)/-8 = (9 + sqrt 129)/8 = 2.5

a = -4, b = 9, c = 3

b^2 - 4ac = 9^2 - 4(-4)(3) = 129

x = (-9 + sqrt129)/-8 = (9 - sqrt 129)/8 = - 0.29

or x = (-9 - sqrt129)/-8 = (9 + sqrt 129)/8 = 2.5
