Algebra is stalking again...
Look the quadratic formula for more clarification
1.The sqaureroot funcn of x basically means the positive number which upon squaring gives x
2.Where as when you want the number which when squared gives x, then it is ±√x
y² = x => y = ±√x (equivalent to statement 2)
k = √m² implies k = |m| (not k = ±m)
"omg who cares what's the use of it" SHUT THE FUCK UP AND ENJOY THE COOL MATH RESULT
And they want to calculate the area of their house
I've been seeing this a lot, and nobody answers it. I don't want a cop out answer like "its defined this way for convenience as this makes the square root operator a function. Plus, if one must consider its negative value, all you have to do is add a negative sign, so there's really no information loss if you know what math you're doing." I want the real MATHEMATICAL reason that the teachers won't teach you. I'm ready to learn. I can take it!
