Write a third degree polynomial with -2 as its only zero

Step-by-step explanation:

It is given that -2 is the only zero of a third degree polynomial. That is

And we can write it in factored form as

Since it is a third degree polynomial, so the multiplicity of -2 must be three. And therefore required polynomial is

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
