If two zeroes of the polynomial x3 – 5x2 + 6x are 2 and 3, then the third zero is A) 0 B) 5 C) 6D) 1

Answer»

Correct option is (A) 0

Let the third zero be \(\alpha.\)

Sum of zeros \(=\frac{-b}a=\frac{-(-5)}1\) = 5

\(\therefore\) \(\alpha+2+3=5\)

\(\Rightarrow\) \(\alpha=5-5=0\)

Thus, the third zero be 0.

Correct option is A) 0
