Question

Verify that 2/5 is a zero of the polynomial f(x)=2- 5x

Answer 1

Step-by-step explanation:

2-5x

-5x=-2

x=-2/-5

x=2/5

So zero of the polynomial is 2/5

Answer 2

For verification of factor of polynomial we should know the factor theorem that when p(x) is divided by (x-a) and p(a)=0; then (x-a)  is a factor of p(x); hence p(x)= 2-5x and (x-a)=(x-2/5); so p(2/5)=2-5×2/5=2-2=0; hence 2/5 is a zero of the polynomial f(x)=2-5x.
