Find the GCF and then factor. -72y-48
First, let's find the greatest common factor (GCF) of -72y and -48.
The prime factorization of -72 is -1 * 2^3 * 3^2 = -72
The prime factorization of -48 is -1 * 2^4 * 3 = -48
The common factors are -1 and 2^3 = 8.
Therefore, the GCF of -72 and -48 is 8.
Next, let's factor out the GCF from the expression -72y - 48:
8(-9y - 6)
Now we can simplify further:
8(-3)(3y + 2)
The factored form of -72y - 48 is 8(-3)(3y + 2)
