3m + 7m + 1 = 10m + 1
-7m - 3m + 5m = -5m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
5 and 7 are two coefficient. And that is all. There is no third coefficient.
3m + 7m + 1 = 10m + 1
-7m - 3m + 5m = -5m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
7m + 2 = 37 or 7m = 37 - 2 or 7m = 35 So m = 5
7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
2(5c + 2d)(5c + 2d)
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
5m-12n
-7m + 20 = -17m - 1010m = -30m = -3
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
