Question

State true or false:

The roots of the equation $24=x^3+x^2+12$ are $2$ and $1$.

• A. True
• B. False

Answer 1

The correct option is B False

We will check whether $2$ and $1$ satisfy this equation or not.

Put $x=1$ in $x^3+x^2+12$,

$1^3+1^2+12=14\ne 24$

so, $1$ is not root of given equation, hence above statement is false.
