Question

Find the zero of the polynomials in the following case: $p\left(x\right)=2x+5$.

Answer 1

Find the zero of the Polynomial:

The given polynomial is $p\left(x\right)=2x+5$.

We know that the zeroes of a polynomial are evaluated by equating them with zero.

$\therefore p\left(x\right)=0$

$\Rightarrow 2x+5=0$

$\Rightarrow$ $2x=-5$

$\Rightarrow$ $x=-\frac{5}{2}$

Hence, the zero of this polynomial is $-\frac{5}{2}$.
