User: Find the solutions of the equation. 1/2x 2 - x + 5 = 0
Weegy: 1/2x^2 - x + 5 = 0
Multiply 2 on both sides:
x^2 - 2x + 10 = 0, with coefficient a = 1, b = -2, c = 10
b^2 - 4ac = (-2)^2 - 4(1)(10) = 4 - 40 = - 36 < 0 (there are two complex solutions)
x = [2 +/- sqrt (-36)/]/2 = 1 +/- 3i
The two solutions are 1 + 3i, 1 - 3i
User: Use the Quadratic Formula to solve the equation. -2x2 - 5x + 5 = 0
Weegy: -2x^2 - 5x + 5 = 0
a = -2, b = -5, c = 5
b^2 - 4ac = (-5)^2 - 4(-2)(5) = 65
x = (5 ? sqrt 65)/-4
x = (-5 - sqrt 65)/4 or x = (-5 + sqrt 65)/4
