Verify whether the values of x given in each case are the zeroes of the polynomial or not?
p(y) = y²; y = 0

p(y) = y²

⇒ p(0) = 0²

⇒ p(0) = 0

∴ Yes y = 0 is the zero of polynomial y².

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

p(x) = x² - 1; x = ±1

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

p(x) = (x - 1)(x + 2); x = -1, -2

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

p(x) = ax + b ;
