Multiply the following using the FoIL method.
(5x-2/5) (5x+1/5)
I got 25x^2-3x+2/25
YOu are almost correct.
when you multiply (5x)(1/5) you get 1x and when you multiply (-2/5)(5x) you get -2x...
so
1x - 2x gives the middle term of -1x

(5x-2/5) (5x+1/5)
I got 25x^2-3x+2/25
when you multiply (5x)(1/5) you get 1x and when you multiply (-2/5)(5x) you get -2x...
so
1x - 2x gives the middle term of -1x
