Me !
( the directions for the top is to factor the following difference of squares. check your answers by foil. the bottom math problems have directions at the top of it )
answer what you can correctly for a brainliest and also get a ! don't answer if you don't know it .

I'm very disappointed and a little depressed that you can't do any of these
twenty problems on your own, and you decided to just dump them on . 
I'm also disappointed that yuu thought the whole thing is only worth 11 points.

I'll do a substantial amount of each problem, but not all of it.
Some of the contribution should be yours.

This whole page is just a bunch of exercises for one fact:

(any difference of two squares) is equal to

         (the sum of the square roots of the terms)
times
         (the difference of the square roots of the terms) .

That's the solution to everything on the page, right there.

OK.  Here we go:

15).  (2c + √5 d) (2c - √5 d)
16).  (7m² + 4) (7m² - 4)
17).  (k³ +  4) (k³ - 4)

18).  (2p² + 5) (2p² - 6)
19).  (11r³ + 1) (11r³ - 1)
20).  (8m² + 3n) (8m² - 3n)

You can do the FOIL checking.  I buried one error in there
just so that you'd have something to look for and fix.

21).  6 (2a + 3b) (2a - 3b)
22).  9x (2x + 1) (2x - 1)
23).  5q (3q + 2) (3q - 2)

24).  2 (4s + 3u) (4s - 3u)
25).  4b (5b + 3) (5b - 3)
26).  3x² (x² + 4) (x² - 4)

27).  8y (x + 2y) (x - 2y)
28).  5m (5m + 1) (5m - 1)
29).  3 (n + 7) (n - 7)

30).  2 (3x + 5) (3x - 5)
31).  m n (m + 1) (m - 1)
32).  4x (2x + 5) (2x - 5)

33).  5n² (4n + 5) (4n - 5)
34).  3 (2n + 1) (2n - 1)

For this second group, I confess that I did them all in my head,
so you should really do some checking just to make sure.
