If coefficients of biquadratic equation are all distinct and belong to the set {–9, – 5, 3, 4, 7}, then equation has
Text Solution
Verified by ExpertsThe correct answer is:
A
Let biquadratic is ax 4 + bx 3 + cx 2 + dx + e = 0
⇒ a + b + c + d + e = 0 as a, b, c, d, e ∈ {–9, – 5, 3, 4, 7}
Hence x = 1 is a root. So real root will be at least two.
