The coefficients here are 4, 32, and -24. The GCF of these values is 4. As for the variables, the values are x^7, x^5, and x^4. The GCF is x^4 To factor this expression take out 4x^4 from each of the terms. Coefficients should be divided by four and exponents should be subtracted by 4 since they have the same base (x). The answer here is A.
