Question

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

Answer 1

Answer:

Given polynomial p(x)=2x−1

We know that p(x) is zero polynomial the value of p(x)=0

∴2x−1=0

Add 1 both sides we get

3x−1+1=1

⇒2x=1

Divided by 2 we get

x=

) is the zero polynomial 2x−1

Answer 2

P(-1/2)= 2(-1/2)+1
-1+1
