Factor the expression 4a2b - 16ab2 + 32a2b2.
First, we need to separate out the factor that is common to all. The numerical coefficient is divisible by 4. All the variables have 'a' and 'b'
= 4a2b - 16ab2 + 32a2b2
= 4ab (a - 4b + 8ab)
So the factor of the expression 4a2b - 16ab2 + 32a2b2 is equal to 4ab (a - 4b + 8ab).
