Factor 12xy-15x+8ky-10k

To factor 12xy - 15x + 8ky - 10k, we can group the terms with common factors:

(12xy - 15x) + (8ky - 10k)

Taking out the common factors:

3x(4y - 5) + 2k(4y - 5)

Now, we can see that we have a common binomial factor of (4y - 5):

(3x + 2k)(4y - 5)

Therefore, the factored form of 12xy - 15x + 8ky - 10k is (3x + 2k)(4y - 5).
