Question

zero of polynomials p(x)=2x+1 is a) 1/2 b) -1/2 c) 2 d) 0​

Answer 1

Answer:

2x+1 = 0

2x = -1

x = -1/2

Option b is the right answer

Sure!!!!

Answer 2

Given:

• There is a polynomial .
• The polynomial is p(x)=2x+1.

To Find:

• The zero of the polynomial.
• The options are

1. 1/2
2. -1/2
3. 2
4. 0

Concept Used:

• We will firstly equate the polynomial with 0 .
• Then we will solve the equation and hence find the zero.

Solution:

Give polynomial is p(x)=2x+1 .

Let p(x)=0.

$\sf{\implies 2x+1=0}$

$\sf{\implies 2x =0-1}$

$\sf{\implies 2x =-1}$

$\sf{\implies x=\dfrac{-1}{2\times 1}}$

${\underline{\boxed{\red{\bf{\leadsto x=\dfrac{-1}{2}}}}}}$

.°. The zero of p(x) is -1/2.
