You can't just square root everything you come across.

>> No.3591441

I square root anything that moves

Basically this I Believe.

The Non-expanded form is incorrect. If you expand it, it SHOULD be:

16-36/2+81/4 = 25-45/2+81/4

>> No.3591446

>>3591342
Right

>>3591387
Failure. Pretend it's 16x^2 -36^x = 25x^2-45x where x=1, except don't put the x=1 until the end. You obviously fail at math.

>>3591427
Half correct... Cockmungler was more specific.

>> No.3591458

(x)² = (-x)²
x = -x

that's what this thing practically says. And x isn't 0.

>> No.3591472

Whenever you take square roots you've got to set up absolute values, right? Or is that with squares?
Help, I'm confus
