1:10 Actually (a - b)^2 = a^2 + b^2 - 2ab.
6:47 Also, isn't sqrt(a^2) = +/- sqrt(-64) ?

[@SALogics]

Very nice! ❤

Unneccessary fumbling about

[@princemensah9731]

Please what about REAL SOLUTIONS? Like a=16 defined for sqrt(a) and a=-16 defined for sqrt(-a)? Please let me know if that is correct or not. Thanks

[@SALogics]

You are very welcome! ❤ √-16 = 4i so 16 and -16 are not the solutions.

Thanks for the feedback. Another lesson learned.
