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
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
x\(^2\) - (sum of roots) x + (product of roots) = 0
x\(^2\) - \(\frac{5x}{2}\) + 4 = 0
2x\(^2\) - 5x + 8 = 0
