Question
Verify whether the following are zeros of the polynomial, indicated against them, or not
p(x) = (x + 3) (x – 4), x = −3, x = 4

Solution
p(x) = (x + 3) (x – 4), x = −3, x = 4
P(–3) = (–3 + 3) (–3 – 4)
= (0) (–7)
= 0
P(4) = (4 + 3) (4 – 4)
= (7) (0)
= 0
∴ – 3 and 4 are the zeros of the polynomial.
