-72=-9s-45 also equals -9s-45=-72
-9s - 45 + 45 = - 72 + 45
-9s = - 27
-9s/-9 = -27/-9
s = 3
Hope this helped!

-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
