Factor: 4a^2b+2ab a^2(b+a) 4a(ab) 2ab(2a+1) ab(ab+1)

To factor the expression $4a^{2}b+2ab$, we need to find the greatest common factor (GCF) of the terms.<br /><br />The GCF of $4a^{2}b$ and $2ab$ is $2ab$.<br /><br />Now, we can factor out the GCF from each term:<br /><br />$4a^{2}b+2ab = 2ab(2a+1)$<br /><br />Therefore, the factored form of the expression is $2ab(2a+1)$.
