Question

can anyone help with
5x+10y 6x+42
______ x _______
7x-49 15x+5y thanks

Answer 1

FOIL the top, like a normal polynomial, and do the same for the bottom

Answer 2

can anyone help with
5x+10y 6x+42
______ x _______
7x-49 15x+5y

Answer 3

factor 5(x+2y) 6(x+7)
-----------x --------
7(x-7) 5(3x+y)
the only thing that cancels is a 5 in the numerator with a 5 in the denominator
6 (x+2y)(x+7)
------------------
7(x-7)(3x+y)

Answer 4

60xy +420y+250x
-------------------------
105x^2 +35xy -735x -245y

Answer 5

Unless it tells you to multiply, I would factor, cancel or simplify what you are able to cancel or simplify and leave the answer in factored form.

Answer 6

thank you!

Answer 7

12xy+84y+50x
------------------------
7xy-49y-147x+105x^2

Answer 8

12xy+12y+50x
---------------
7xy-7y-147x+105x^2

Answer 9

You could take Mr.Joselson's answer, take the x + 7, remove a - making -6 and x-7, cancelling out the 2 x-7's and ending up wiht the answer \[-6(x+2y)/ 7(3x+y)\]

Answer 10

if you make the 6 negative it becomes -6(-x-7) which still can not be cancelled
