Question

Show that x minus 2 is a factor of the polynomial f x is equal to 2 x cube minus 3 x square - 7 x + 30 and hence factorise FX

Answer 1

Answer:

Given: f(n) = 2n^3- 3n^3 -7n+30

Let g(n) = n-2 will be factor of f(n).

g(n)= 2

we we put g(n) in f(n) it was not equal to zero since we conclude the this is not factor of f(n).

... bro pls check your question.
