DedPeter [7]

Answer:

3xy(2xy-1)

Step-by-step explanation:

We have been given an expression 6x^2y^2-3xy. We are asked to factor our given expression.

We will factor out greatest common factor of both terms.

We can see that both terms share a common factor that is 3xy.

We can rewrite terms of our given expression as:

3*2x*xy*y-3xy

Factor out 3xy:

3xy(2xy-1)

Therefore factorized from of our given expression would be 3xy(2xy-1).
