The solution to the quadratic equation 5 + 3x – 2×2 = 0 is

The solution to the quadratic equation 5 + 3x – 2x2 = 0 is
  • A.
    ((frac{5}{2}), 1)
  • B.
    (5, 3)
  • C.
    -((frac{5}{2}), -1)
  • D.
    ((frac{5}{2}), -1)
Correct Answer: Option D
Explanation

5 + 3x – 2x2 = 0, (x + 1)(5 – 2x) (expand to check)
(x + 1)(5 – 2x) = 0
when x = 1 = 0, x = -1
when 5 – 2x = 0, x = (frac{5}{2}) – 1
