Simplify. I dont really know where to start. I have never had to do a problem like this and my lesson isn't thorough enough to explain it. (4x + 3y) - (2x -5y) "make sure to distribute the - into the second set of parentheses"
do you know how to distribute?
FOIL method right?
no
FOIL is a memory device that can be used if you can remember it, when you are multiplying
we are not mutliplying (a+b)(c+d) we are subtracting
right.
so, it might help to stack the terms ... (a + b) -(c + d) --------- summ now it should look like a familiar subtraction problem, does it?
yes it does. do i subtract d from b and c from a?
this is just to present a format, but yes thats the idea. you want to make sure your doing that with your own like terms tho
(4x + 3y) -(2x - 5y) ---------- 4x - 2x and 3y -- 5y
I came up with the answer of 2x+8y.
that is correct
Thanks for your help!! :)
youre welcome, and good luck ;)
