Question

Factor a^3+3a-a-3

Answer 1

Do you know the factor theorem and how to do long division or synthetic division of polynomials?

Answer 2

Yes

Answer 3

Oh, then you cannot solve this. What section are you on? Have you been attending class?

Answer 4

Is there a typo in the polynomial. Should it read\[a^3+3a^2-a-3\]

Answer 5

If it is like what @ospreytriple put:
\(a^3+3a^2−a−3\)
try grouping:
\(a^3+3a^2~~−~~(a+3)\)
and I'll let you finish the factoring.
