Question

verify whether the following are zeroes of the polynomial indicated against them​

Answer 1

Step-by-step explanation:

p(x):5x-4a-x

p(a):5×a-4a-a

p (a) :5a-4-a

p (a) : 5a-5a=0

since x=a is zero of polynomial

p(x):x2-1

p(-2):(-2)2-1

p(-2):-4-1=-5

since x=-2 is not the zeros of polynomial
