Algebra 2 Help

[JRP]

hey, well we are doing the sum and difference of square/cubed numbers, and this stuff confuses the hell outta me. We have a quiz on thursday on everything. Does anyone have any hints, or easy ways on doing it? Thanks

there are formulas for determining the sum and difference of cubed numbers and squared in the back and front of your text book probably. I don't know the off the top of my head, but probably should since i'm in Calc 2 right now.. lol

na, theres nothing in there. Like i know you have to see if there is a GCF first, then factor them, but damn, i hate this stuff sooo much. Like once i start i loose all sense of concetration and forget everything. And like i know when u do a sum/diff of a cube you do a binomial times a trinomial, and i know where to put the signs like if the sign in the problem is a + then you would do ( + ) ( - +)

haha jordan my teacher failed me last year for ALG 2 ( i knew it all but i f'ed around in class) and took it in summer school, so i took it twice......

i hope this thread stays alive, i need some help in algebra 2 myself. i would try and help but i dont think were that far in the book yet as you are. and plus i have a 53/F in there so asking me would be pointless:ermm:

i don't remember exactly how to do it... i'm already in multivariable calculus 3... but i can give u some hints to calc..


#1 stay organized!!!! thats the number one problem most people have with math...


#2 look for patterns u can reconize... when u sit down and look at a problem try and thing where u've seen something like it before... relate it to something u know!

#3 make flashcards with the formulas... u should know them like u know who is in the pro class of the GNCs and GNCCs:blah:


in h.s. i was failin outta math... i couldn't do anything... but eventually u figure out what works for u...

Were doing the same thing and heres the "forumlas"...don't know if this is what youre looking for(btw x2=x squared x3=x cubed)..
Differrence of 2 squares- x2-y2=(x+y)(x-y)
Examples-
x2-9=(x+3)(x-3)
x2-81=(x+9)(x-9)
For these remember x2=x squared, # in front of x is the coefficent
4x2-25y2=(2x+5y)(2x-5y)

Difference of 2 cubes- x3+y3=(x+y)(x2-xy+y2)-again remember x2 and y2 means squared...I can get examples of the cubes if you want...hope this helps
