Question

find a zero of the polynomial p(x)=2x+1​

Answer 1

Zero of $\bf p(x) = 2x + 1$ is -1/2.

Given:

• $p(x) = 2x + 1$

To find:

• Find zero of p(x)

Solution:

Step 1:

To find zero of polynomial, equate the polynomial to zero.

i.e.

$p(x) = 0$

or

$2x + 1 = 0$

Step 2:

Solve for x.

$2x = - 1$

or

$x = \frac{ - 1}{2}$

Thus,

Zero of polynomial p(x)=2x+1 is -1/2.

Answer 2

Given,

p(x) = 2x + 1

To find,

Zero of the polynomial p(x) = 2x + 1.

Solution,

The zero of the polynomial p(x) = 2x + 1 is -1/2.

We can easily solve this problem by following the given steps.

Now, we know that to find the zero of the polynomial we need to equate it to zero.

So, it will be

2x + 1 = 0

2x = -1 ( Moving 1 from the left-hand side to the right-hand side will result in a change of its sign from plus to minus.)

x = -1/2

(Zeros of a polynomial are the values that make the value of the polynomial to be zero. For example, if we put the value of x (-1/2) in the polynomial p(x) = 2x + 1, its value will be zero.)
