Looks like you know your work -
[quote]X squared + 4x + 16 = 0 Solve for x[/quote] X * X + 4 * x + 16 = 0 There is no solution.
-
X = 0
-
My ass
-
Assume solving this equation over Complex plane, there will be 2 solutions.
-
Edited by nopenopenope: 3/29/2016 2:10:34 PMX=-2 + or - sqrt 4-16. So, X = -2 + or - sqrt 12i?
-
Is x = -2 then x2 + 4x + 16 = 12

Okay... I can do ^ on my phone too, but it's easier to do ². -
(X+4)(x+4)

Why did you type out squared instead of ^2

Because I can -
If you wanted this to work out evenly you wrote the problem wrong

I didn't want it to work evenly, otherwise it'd be a -
A what?

People are idiots just use quadratic formula I'm too lazy rn tho...
