this is not how proofs work, and your evaluation is also incorrect. downvoted

Precedence of operations. You have to take the square roots first before you can multiply i.e. √a × √b ≠ √(ab) in general, as that violates operator precedence. It's a nice shortcut when a and b are both positive reals though, since it gives the same answer as if you had followed proper operator precedence.

Good video, but √36 is ±6, so √-9 * √-4 = √36 = -6

1:43 on top of the horrible handwriting you are using a thick pen. Totally Aweful

nice proof, but you misspelled breaking in the title. You said "braking", as in like pressing the brakes.

The trick is this: a^2 + b^2 -2ab = (a-b)^2 = (b-a)^2; in the left side you choose (b-a)^2 while in the right side you choose (a-b)^2. The initial choice of diferences are then treated as two squares from which roots are extrated which returns four solutions of which only one is consistent.
