To factorize the expression \(32x + 40\) fully, you can first factor out the greatest common factor (GCF), which is \(8\).
So, \(32x + 40 = 8(4x + 5)\).
Now, the expression \(4x + 5\) cannot be further simplified because there are no common factors other than 1. Therefore, the fully factorized form of \(32x + 40\) is \(8(4x + 5)\).
