The sum of the root of a quadratic equation is (frac{5}{2}) and the product of…

The sum of the root of a quadratic equation is (frac{5}{2}) and the product of its root is 4. The quadratic equation is

  • A.
    x + 8x2 – 5 = 0
  • B.
    2x2 – 5x + 8 = 0
  • C.
    2x2 – 8x + 5 = 0
  • D.
    x2 + 8x – 5 = 0
Correct Answer: Option B
Explanation

x2 – (sum of roots) x + (product of roots) = 0
x2 – (frac{5x}{2}) + 4 = 0
2×2 – 5x + 8 = 0
