Are the following statements 'True' or 'False'? Justify your answers.
If two of the zeroes of a cubic polynomial are zero, then it does not have linear and constant terms.
Given:
If two of the zeroes of a cubic polynomial are zero, then it does not have linear and constant terms.
To do:
We have to find whether the given statement is true or false.
Solution:
Let $\alpha, \beta$ and $\gamma$ be the zeroes of a cubic polynomial p(x).
Given that two of the zeroes are zero.
Let $\alpha=\beta=0$ and $\gamma=a$
Therefore,
$p(x)=(x-\alpha)(x-\beta)(x-\gamma)$
$=(x-0)(x-0)(x-a)$
$=x^{3}-a x^{2}$ which does not have linear and constant terms.
Hence, the given statement is true.
