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 + 8x^{2} – 5 = 0 
B.
2x^{2} – 5x + 8 = 0 
C.
2x^{2} – 8x + 5 = 0 
D.
x^{2} + 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
