Question

3.
Verify that x = 3 is the zero of the polynomial: P(x) = x - 2x² –x - 6

Answer 1

Step-by-step explanation:

x=3

p(3)= 2- 2(3) - (3) - 6

p(3) = 2-6 -3 -6

p(3)= -13

no it not the zero of given polynomial

Answer 2

no

if p(x)= 0 , then it si a zero of the polynomial

hope understood
