Question

Verify weatherthe following are zeros of the polynomial indicated against them or not. P(X)=(X+3) (X-4), X=4, X=-3

Answer 1

Answer:

(i)  (a) x+3 = 4+3=7 ≠ 0, ∴ 4 is not a zero of x+3

    (b)x+3 = -3+3=0 ∴ 3 is a zero of x+3

(ii) (a) x-4 = 4-4=∴ 4 is the zero of x-4

    (b) x-4 = -3-4=-7 ≠ 0, ∴ -3 is not a zero of x-4
