Factor completely 5a^2+b Primo a(5a+b) b(5a^2) ab(5a+1)

To factor the expression completely, we need to look for common factors and factorable patterns. First, let's examine the given expression: We can see that there are no common factors between the terms and . Additionally, this expression does not fit any standard factoring patterns such as the difference of squares, perfect square trinomials, or factoring by grouping.Since there are no common factors and no standard factoring patterns that apply, the expression is already in its simplest form and cannot be factored further.Therefore, the correct answer is:
