please help?

Question

1: Today you will actually factor out GCFs, like in yesterday's websites. Review there if necessary.
Factor out the GCF and choose the appropriate answer for each.

x2 + x

x(1x)
x(x2 + 1)
x(x + 1)


2: 2x2 + 2x + 2
2(x2 + x + 1
2(x + 1)
2(x2 + x)


3: x5 + x2
x(x3 + 1)
x2(x3 + 1)
x(x2 + 1)


4: x3 + 2x2
x (x2 + 2)
x2(x + 2)
x(x + 2)


5: 5x5 + 5x2
5x2 (x3 + 1)
x2 (x3 + 1)
5x2 (x2 + 1)


6: 6x2 + y2 + 6x
6x (x + y + 1)
x (6x + y + x)
There is no GCF


7: 5x2 - 10x + 2
There is no GCF
5x (x + 2 + 1)
2 ( 3x2 + 5 + 1)


8: 11x5 + 8x4 - 13x3 + 4x2
x(11x3 + 8x2 - 13x + 4)
x2 (11x3 + 8x2 - 13x + 4)
x2 (11x2 - 13x + 4)


9: -13x2 - 5x + 7
7 (-6x - 5 + 1)
5x ( -8x - 1 + 2)
There is no GCF


10: -9x2 + 6x - 3
3(3x2 + 2x - 1)
-9x2 + 2x - 1
3(-3x2 + 2x - 1)


11: 2x2 + 10x - 2
2(x2 + 5x - 1)
2(5x - 1)
10(x2 + 5x - 1)


12: -9x7 + 15x4 - 9x3 + 12x - 12
3(-x76 + 5x4 + 3x2 + 4x - 4)
3(-3x7 + 5x4 - 3x3 + 4x - 4)
There is no GCF


13: 20x + 34
2(10x + 16)
2(10x + 17)
2(5x + 17)


14: 20x + 14
2(10x + 7)
5(2x + 7)
2(5x + 7)


15: 10x + 15
5(2x + 15)
There is no GCF
5(2x + 3)

Answer 1

omg its summer vacation...HOW COULD YOU EVEN DREAM OF DOING THAT???LOL

Answer 2

1)x2 + x=x(x+1)

2)2x2 + 2x + 2=2(x2+x+1)

3)x5 + x2=x2(x3+1)

4)x3 + 2x2=x2(x+2)

5)5x5 + 5x2=5x2(x3+1)

6)6x2 + y2 + 6x There is no GCF since the variables are different

7)5x2 - 10x + 2 There is no GCF

8)11x5 + 8x4 - 13x3 + 4x2=x2(11x3+8x2-13x+2)

9)-13x2 - 5x + 7 There is no GCF

10)-9x2 + 6x - 3=3(2x-1-x2)

11: 2x2 + 10x - 2=2(x2+5x+1)

12: -9x7 + 15x4 - 9x3 + 12x - 12=3(-3x7+5x4-3x3+4x-4)

13: 20x + 34=2(10x+17)


14: 20x + 14=2(10x+7)

15: 10x + 15=5(2x+3)

Answer 3

You have to factor and figure out what is in common. Take number 11.

2x^2 = 2 * x * x
10x = 2 * 5 * x
2 = 2

The only thing in common is 2, so that is the greatest common factor.

2 * (x^2 + 5x - 1)
