Which statement is true about this quadratic equation? y = –2x^2 + 9x-12

A. There are two real solutions.
B. There is one complex solution.
c. There is one real solution.
D. There are two complex solutions.

There are two real roots because b²>4ac

in the equation, b²= 9² = 81.

4ac = 4×-4×-12= 72

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
