how do u factor 5w^2-35w+60=0
if u could...can y plz explain it..i keep getting 3 ansers instead of 2

  • algebra 2 -

    Start by factoring out a 5 from each term. What do you come up with?

  • algebra 2 -

    i got 5(w^2-7w+12)=0...is that right?..and then do i factor the middle?...but when i did i get 3 answers

  • algebra 2 -

    Yes, that's good.

    You're going to want something in the form (__ + __)(__ + __)
    One or both of the signs could be negative, though.

    Look at the 12. What are its two closest factors? When added, do they equal 7?

    You can check yourself by using the FOIL method after you come up with your factorization. Now, what do you get?

  • algebra 2 -

    I should mention that you are ignoring the 5 now and working solely with w^2-7w+12.

    i got 5(w-3)(w-4)...that i totally understand...now i put 5=0 w-3=0 and w-4=0...hmm...i see wat i did now..one last question wat do i do with the 5=0?

  • algebra 2 -

    You just ignore the 5, as 5 cannot equal 0. Your answers are just w = 3 and w = 4.
