Question

find the zero of the polynomial p(x)=2x+5

Answer 1

Answer:

$-\frac{5}{2}$

Step-by-step explanation:

We have been given the polynomial p(x)=2x+5.

Zero of the polynomial is the x-intercept. Hence, in order to find the zero of the polynomial, we set p(x)=0

Therefore, we have

$2x+5=0$

Subtract 5 to both sides

$2x=-5$

Divide both sides by 2

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

Therefore, the zero of the polynomial p(x)=2x+5 is $-\frac{5}{2}$

Answer 2

Answer:

$The \:zero \:of \:the \:given \\polynomial \:p(x) \:is \:\frac{-5}{2}$

Step-by-step explanation:

Given polynomial p(x)=2x+5

To find zeroes,

Let p(x) = 0

=> 2x+5 = 0

/* subtract 5 from both sides of the equation ,we get

=> 2x+5-5 = -5

=> 2x = -5

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

Therefore,

$The \:zero \:of \:the \:given \\polynomial \:p(x) \:is \:\frac{-5}{2}$
