42ax + 36ay – 7b²x – 6b²y

Solution:-

(42ax + 36ay) – (7b²x + 6b²y)

Here we can factor out 6a from first group

6a (7x + 6y) - (7b²x + 6b²y)

In second group, b² can be factored out

6a (7x + 6y) – b²(7x + 6y)

Now we have (7x + 6y)in common and can be factored out.

(7x + 6y) (6a – b²)

So (7x + 6y) (6a – b²) are the factors of the polynomial 42ax + 36ay – 7b²x – 6b²y.
