SOLUTION: x^4+7000x. Solve with the quadratic formula In the end i always get (-10+/-(i sqrt(300)))/2, but it says I should have -5+/-5i sqrt(3). How do you get that?

Question 878324: x^4+7000x. Solve with the quadratic formula
In the end i always get (-10+/-(i sqrt(300)))/2, but it says I should have -5+/-5i sqrt(3). How do you get that?

You can put this solution on YOUR website!
Can't solve it with the quadratic formula as is.
Is it x%5E4%2B7000x%5E2=0 or is it x%5E4%2B7000=0?
Working backwards from the solution you provided doesn't get me closer either.
