Question

Find the zero of a polynomial 2x + 4.

Answer 1

Assume the given polynomial as,

`P(x)\text{ = 2x + 4}`

The zero of the given polynomial is calculated as,

`P(x)\text{ = 0}`

Therefore,

`\begin{gathered} 2x\text{ + 4 = 0} \\ 2(x\text{ + 2) = } \\ x\text{ + 2 = 0} \\ x\text{ = -2} \end{gathered}`

Thus the zero of the given polynomial is -2 .
