Question

Can someone help me for a medal and fan?

Answer 1

Factor completely 5x2 + 20x.

Answer 2

To start, 5x^2 + 20x can by simplified by taking out a 5 -> 5(x^2+4x). But you can also take out an x so the final answer would be 5x(x+4)

Answer 3

Okay, thanks. Can you help with a quick one also?

Answer 4

Sure

Answer 5

I always get confused with the whole finding the greatest common factor thing, so can you tell me what the greatest common factor of 8 and 36 is? Is it 8, 4, or 2?

Answer 6

Or is it 6?

Answer 7

Oh, wait forget about the 8. Just realized 8 doesn't go into 36.

Answer 8

Yeah, so the answer would be 4. 8 goes into 8 but not 36, 7 goes into neither of them, 6 goes into 36 but not 8 ... so for finding the GCF all you're looking for is the largest number that goes into both numbers.

Answer 9

Okay, thanks.
