Question 108856: I know this is the righ secton for my quesiton, but I don't think the area for putting your questions is good, this is factoring. how do you factor these using -difference of squares - difference of cubes - sum of cubes -or split the middle
3y cubed - 192y
24X squared + 12 y sqaured
6my - 2ab + 2am - 6by
ac+ bd + bc + ad
x to the 6th -81
49g2 - 81hto the 4th
and
4ax - 14 bq - 35by - 10 ay
thank you so much

:

; factor out 3y, now you have the difference of squares

; that's about all you can do with it
:
6my - 2ab + 2am - 6by
:
6my - 6by + 2am - 2ab; regroup
:
6y(m - b) + 2a(m - b); factored out 6y and 2a
:
(m - b) (6y + 2a); factored out (m-b)
:
:
ac+ bd + bc + ad
:
ac + ad + bd + bc; regroup
:
a(c+d) + b(d+c); factored out a and b
Same as
a(c+d) + b(c+d);
:
(c + d)(a + b); factored out (c+d)
:

Difference of squares:

:

Difference of squares

:
4ax - 14 bq - 35by - 10 ay
:
4ax - 10ay - 14bq - 35by; regroup
:
2a(2x - 5y) - 7b(2q + 5y); change the sign inside the brackets
