Answer 1

12b* b-1/4 +14* b²-2b/21 - b-b²/3=

12b*(b/4-1/4)+14* b²-2b/21 - b-b²/3=

12b*(b/4-0,25)+14* b²-2b/21 - b-b²/3=

(3b-3)b+14* b²-2b/21 - b-b²/3=

3b²-3b+14* b²-2b/21 - b-b²/3=

3b²-3b+14*(b²/21-2b/21)- b-b²/3=

3b²-3b+14*(b²/21-2/21b)- b-b²/3=

3b²-3b+2/3b²-4/3b- b-b²/3=

11/3b²-3b-4/3b- b-b²/3=

11/3b²-13/3b- b-b²/3=

11/3b²-13/3b-(b/3-b²/3)=

11/3b²-13/3b-b/3+b²/3=

11/3b²-14/3b+b²/3=

4b²-14/3b
