-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
--------------
-4
x = 3 + 3i√7 x = 3 - 3i√7
------------ ------------
4 4
I think the answer is the second one. A reflection over the x-axis and the a 90° counterclockwise rotation about the origin.
If it is repeating then it is 5/9 but if it is just 0.5 then 1/2
Quotient is Latin for "how many times" and it is the answer to a division problem.
560/7=80
we can prove this by doing it backwards
7*80=560
