Question 472407
10xy - 15x 

GCF of 10 and 15 is.....5
GCF of x and x is.......x 
there is no y in the 2nd term, therefore it is not included in the GCF 


GCF = 5x 


- when you factor out the GCF, divide each term by it and that's what is left in parentheses 


= 5x(2y - 3) {factored out the greatest common factor}
