When factoring, look to see what you can take out of a parentheses to put out front of it. It is the opposite of distributing in polynomial expressions. The first term 5x can be factored (5)(x). The second term 15 can be factored (5)(3). 5 is the only factor common to both terms. Divide out the 5 from the terms and move the common factor to the front of the parentheses. Remember, when dividing 15 by 5, a 3 is left over. 5x/5 - 15/5 = x - 3 Move the common factor to the front. 5(x - 3) Incorrect answer. Please choose another answer.
