User: If (x + 1)(x - 3) = 5, then which of the following statements is true?

User: Which of the following equations has only one solution? x 2 = 9 x(x - 1) = 9 x 2 - 6x + 9 = 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
