Question

Check whether 2 is a zero of the polynomial p(x) = x? - 2x² + 4x + 1​

Answer 1

Answer:

Concept: If a is a zero of the polynomial $p(x)=2x^2+4x+1$

then $p(a)=0$

Given: $p(x)=2x^2+4x+1$, $a=2$

To find: whether a is a zero of the polynomial, $p(x)=2x^2+4x+1$

Step-by-step explanation:

p(x)=2x^2+4x+1

$p(2)=2(2)^2+4(2)+1$

$= 8+8+1$

$=17$

Answer 2

Given ; p(x) = 2x² + 4x + 1​

To Find ; whether 2 is a zero of the polynomial p(x) = 2x² + 4x + 1​

Solution ;  p(x) = 2x² + 4x + 1​

We can check whether a number is a zero of a polynomial by putting that value of x in the equation. It is the easiest method to solve these types of questions just put the value and check

p(x) = 2x² + 4x + 1​

p(2)= 2*4 + 8 +1

= 17

Hence it is not a zero of polynomial
