Question

Verify whether x=3 is a zero of the polynomial p(x) = 4x2 + 7x + 1. Also find the value of p(–2)

Answer 1

Hello mate!!!!!!!

Here is your answer......

P(x) = 4x^2 +7x +1

Putting x = 3

P(3) = 4 (3)^2 +7×3 +1 = 36+21+1 = 58

Therefore x = 3 is not a Zero of given p(x)

Now, putting x = -2

P(-2) = 4(-2)^2 +7×(-2)+1 = 16 -14 +1 = 3

So p(-2) = 3

HOPE THIS WILL HELP YOU : )

Answer 2

Answer

Step-by-step explanation:

Put the value of x in the polynomial

X=3

4x^2+7x+1

36+21+1=58

Hence 3 is not the zero of the given polynomial.

Now,

P(-2)=16-14+1=3
