x^2+4x that is equal to or more then 5

Question

anonymous · Answer

$$x ^{2}+4x \ge5$$

anonymous · Answer

the sign is means "greater than or equal to" just for further reference....
anyways can you tell me how you would solve:
$$x^2 + 4x = 0$$?

anonymous · Answer

i know the sign. and no, i dont get it because it has two x's. I am not good with factoring but maybe its like |dw:1383672448527:dw| but after that idk, and idk if thats even right.. any help is great. But would prefer to be shown how to do t not just the answer

I am here to show you thats why I asked. My mistake I make a slight copy error I should have said how would you solve:
$$x^2 +4x = 5$$

anonymous · Answer

sorry about that :P

anonymous · Answer

its fine, um.. i know i am suppose to factor it.. i think, i am just not sure how. its |dw:1383672751483:dw| is the same as $$x ^{2}+4x \ge5$$ correct?
