Answer 2

Answer:

p(x) = x + 5 Let p(x) =0, then, p(x) = x + 5 = 0 x = 0 – 5 ∴ x = -5 -5 is zero of p(x). (ii) p(x) = x – 5 If p(x) = 0, then p(x) = x – 5 = 0 x = 0 + 5 ∴ x = 5 5 is the zero of p(x). (iii) p(x) = 2x + 5 If p(x)= 0, then p(x) = 2x + 5 = 0 2x = – 5 ∴ x = − 5 2 −52 − 5 2 −52 is the zero of p(x). p(x) = 3x – 2 If p(x)= 0, then p(x) = 3x – 2 = 0 3x = 2 ∴ x = 2 3 23 2 3 23 is the zero of p(x). (v) p(x) = 3x If p(x) = 0, then p(x) = 3x = 0 ∴ x = 0 3 03 0 3 03 is the zero of p(x) (vi) p(x) = ax, a ≠ 0 If p(x)= 0, then p(x) = ax = 0 ∴ x = 0 a 0a ∴ x = ∞(infinity) ∞ is the zero of p(x). (vii) p(x) = cx + d, c ≠ 0, c, d are real numbers If p(x)= 0, then p(x) = cx + d = 0 cx = 0 – d cx = -d ∴ x = - d c dc is the zero of p(x).
