Question

Show that 2 and –

1

3

are zeroes of the polynomial 3x2

– 5x – 2.​

Answer 1

Answer:

only 2 is zero of polynomial

Step-by-step explanation:

for x = 2

p(x) = p(2) = 3(2)2 - 5(2) - 2 = 12 - 10 -2 = 0

Therefore, 2 is a zero of polynomial p(x).

for x = 1

p(x) = p(1) = 3(1)2 - 5(1) - 2 = 3 - 5 - 2 = -4

Therefore, 1 is not a zero of polynomial p(x).

for x = 3

p(x) = p(2) = 3(3)2 - 5(3) - 2 = 27 - 15 - 2 = 10

Therefore, 3 is not a zero of polynomial p(x)
