Q2 of 90 Page 27

For each polynomial of the following polynomials, find the value of p(2), p(1) and p(0).

p(y) = (y+1) (y-1)

p(2) means substitute value 2 in the polynomial in place of variable


p(1) means substitute value 1 in the polynomial in place of variable


p(0) means substitute value 0 in the polynomial in place of variable


p(y) = (y + 1) (y-1)


the variable is y substitute it with values 2, 1 and 0 to find p(2), p(1) and p(0) respectively


p(2)


⇒ p(2) = (2 + 1)(2 – 1)


⇒ p(2) = (3)(1)


⇒ p(2) = 3


p(1)


⇒ p(1) = (1 + 1)(1 – 1)


⇒ p(1) = (2)(0)


⇒ p(1) = 0


p(0)


⇒ p(0) = (0 + 1)(0 – 1)


⇒ p(0) = (1)(-1)


⇒ p(0) = -1
