Question 197472: HeLLo! And if you are helping me.... I truly appreciate it! Im having a hard time with FACTORING!! Im in Math098...i am a freshman in college!! MAth is not my subject and it is very depressing for me... So if you can help me... or answer the questions... I will gladly appreciate it...
AGAIN... This is factoring....
I cant make an exponent so instead I will do something like this... EXAMPLE: 2^2

1.) 3-x+xy-3y
2.) 2x^3+8x^2+6x
3.) x^2+4x+5
4.) 8x^2+6x-9
5.) 12x2-x-20
6.) -24x^3-42x^2+45x
7.) 2x^2-x-1
8.) 6x^2+9x+4x+6
9.) 6x^2+x-1
10.)16+16x+3x^2
11.) x^2-22x+121
12.) 9x^2-4z^2
13.) x^2-8x+16
14.) -10x^2+3x+1

Thank you sooo much... please help!! I need this by 5/24/09...
Sunday afternoon!! Thanks!!

1.) 3-x+xy-3y
(3-x) -y(3-x)
(3-x)(1-y)
-----------------------
2.) 2x^3+8x^2+6x
2x(x^2 + 4x + 3)
2x(x+3)(x+1)
------------------------------
3.) x^2+4x+5
Requires the quadratic formula:
---------------------------------
4.) 8x^2+6x-9
8x^2+12x - 6x - 9
4x(2x+3) -3(2x+3)
(2x+3)(4x-3)
-----------------------------------
5.) 12x2-x-20
12x^2 - 16x + 15x - 20
4x(3x - 4) + 5(3x-4)
(3x-4)(4x+5)
-----------------------------------
6.) -24x^3-42x^2+45x
x(-24x^2 - 42x + 45)
-x(4x + 3)(6x - 15)
----------------------------
7) 2x^2-x-1
2x^2 -2x + x -1
2x(x-1)+ (x-1)
(x-1)(2x+1)
-------------------------------
Now maybe you can figure out the rest of these:
Cheers,

8.) 6x^2+9x+4x+6
9.) 6x^2+x-1
10.)16+16x+3x^2
11.) x^2-22x+121
12.) 9x^2-4z^2
13.) x^2-8x+16
14.) -10x^2+3x+1
