(a - t/2)^2 = (b - t/2)^2
To:
a - t/2 = b - t/2
Where a, b, and t are variables for all real numbers, then yes, you are...
Well, you're excluding have the input set, the half where either a-t/2 is negative, or b-t/2 is negative.
So I guess when I take I take:
[tex]\sqrt(1-2)^2[/tex] or
[tex]\sqrt(-3)^2[/tex]
(the line should be over everything but I'm not great with latex.
I'm taking the square root of a negative number... interesting; never learned that in math.
Let's see what happens when we follow order of operations:
[tex]\sqrt(-3)^2=
\sqrt(9)=+/-3[/tex]
Where do we take the square root of any negative number?
