Answer:
The required factors are: x, (x + 6) and (x - 3).
Step-by-step explanation:
As per the question,
The given polynomial is:
Now,
BY factorization, we get
By splitting the mid-term, that is split 3x like:
3x = 6x - 3x
Therefore,
Now on further solving by taking common factor out, we get
Therefore, the given second polynomial (x - 4), is not a factor of given polynomial .
Hence, the given polynomial has three factor x, (x + 6) and (x - 3).
