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

To factor the expression \(5a^2 + b\) completely, we need to look for common factors and factorable patterns. <br /><br />First, let's examine the given expression:<br />\[ 5a^2 + b \]<br /><br />We can see that there are no common factors between the terms \(5a^2\) and \(b\). Additionally, this expression does not fit any standard factoring patterns such as the difference of squares, perfect square trinomials, or factoring by grouping.<br /><br />Since there are no common factors and no standard factoring patterns that apply, the expression \(5a^2 + b\) is already in its simplest form and cannot be factored further.<br /><br />Therefore, the correct answer is:<br />\[ \text{Prime} \]
