Find the ratio of X to Y in the following: x^2+y^2=(x+2y)^2

-3 : 4

Step-by-step explanation:

x² + y² = (x + 2y)²

x² + y² = x² + 4xy + 4y²

4y² - y² + 4xy = 0

3y² + 4xy = 0

y(3y + 4x) = 0

3y + 4x = 0

3y = -4x

x/y = -3/4

x : y

-3 : 4

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
