Hey, help me when you get the chance. Thanks you so much.

21. JuanitaM

ok - so first lets remove the parenthesis and get all terms with x on one side. so do you follow me up to that line above

22. Tia1977

yes

23. JuanitaM

24. JuanitaM

note that for completing the square there can not be ANY coeffficient in front of x^2 so divide EACH term to remove the coefficient ....

25. Tia1977

ok

26. JuanitaM

|dw:1330628383084:dw|

27. JuanitaM

now to get the square of a fraction - you are basicallly multiply by 1/2 and that is where the 9/4 came from..... follow?

28. Tia1977

yes.

29. JuanitaM

30. Tia1977

i got lost in the step that follow this one

31. JuanitaM

so hear - you must ADD the square on both sides. hence the (9/4)^2 on both sides ..... right?

32. Tia1977

ok.

33. JuanitaM

on the left side you must add fraction by putting over common denomiator =
