Question

p(x) = x2 - 1; x= +-1 verify whether value of x is zero of the polynomial or not​

Answer 1

SOLUTION

GIVEN

p(x) = x² - 1

TO CHECK

x = - 1 , 1 whether value of x is zero of the polynomial or not

EVALUATION

Here the given polynomial is

p(x) = x² - 1

Now Putting x = - 1 we get

$\sf{p( - 1) = {( - 1)}^{2} - 1 = 1 - 1 = 0}$

So - 1 is a zero of p(x)

Again Putting x = 1 we get

$\sf{p( 1) = {( 1)}^{2} - 1 = 1 - 1 = 0}$

So 1 is a zero of p(x)

Hence - 1 and 1 are zeros of p(x)
