Verify whether the values of x given in each case are the zeroes of the polynomial or not?
p(x) = 2x + 1;

p(x) = 2x + 1

⇒ p(-1/2) = 2(-1/2) + 1

⇒ p(-1/2) = -1 + 1

⇒ p(-1/2) = 0

∴ Yes x = -1/2 is the zero of polynomial 2x + 1.

Find p(0), p(1) and p(2) for each of the following polynomials.

p(t) = (t - 1) (t + 1)

Find p(0), p(1) and p(2) for each of the following polynomials.

p(x) = x² - 3x + 2

Verify whether the values of x given in each case are the zeroes of the polynomial or not?

p(x) = 5x - π;

Verify whether the values of x given in each case are the zeroes of the polynomial or not?

p(x) = x² - 1; x = ±1
