Question

Find the zeros of the polynomial in each of the following cases:

(iii) $P\left(x\right)=x+4$

Answer 1

Calculation of the zeros:

Zeros: The zeros of a polynomial are those values of the variable which makes the polynomial zero.

Equate the polynomial $P\left(x\right)$ to 0 and solve for $x$ to obtain the required value.

$$\begin{gathered} P\left(x\right)=0 \\ \Rightarrow x+4=0 \\ \therefore x=-4(Subtracting4frombothsides) \end{gathered}$$

Final Answer: The zero of the given polynomial is $-4$.
