Find The Integer Without Actual Division Prove That Is Exactly Divisible By .
Step 1: Find the factors
Given Polynomials: and.
Let and
Then,
This means and are factors of.
Step 2: Find the values of.
At, the value of is,
So, by factor theorem we can say is a factor of.
At the value of is,
So, by factor theorem we can say is a factor of.
As both and are factors of the given polynomials and
So we can say Is Exactly Divisible By.
Hence proved.
