Can someone help me for a medal and fan?

Question

anonymous · Answer

Factor completely 5x2 + 20x.

anonymous · Answer

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)

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

anonymous · Answer

Sure

anonymous · Answer

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?

anonymous · Answer

Or is it 6?

anonymous · Answer

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

anonymous · Answer

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.
