Directions: Using the digits 0 to 9 at most one time each, place a digit in each box to make both expressions factorable.
If you can only find a few solutions, have you considered expressions where you first factor out the GCF?
36, 49 and 01, 27
25, 36 and 64, 01
There are a lot (not infinite) of solutions once you include taking out the GCF.
36x^2 – 09y^2 –> 9(4x^2 -1y^2) –> factorable!
81a^3 + 24b^3 –> 3(27a^3 + 8b^3) –> factorable!
