By the completion or non-completion – This refers to seeing a whole thing even if that whole is not actually there.It is also known as Puranapuranabyham and is used to simplify or solve algebra problems.
a simple quadratic will be in the form of (x + *some number*)3
By estimating ,
x3 + 3x2 + 3x + 8
estimate #2: (x + 2)3 This works out to x3 + 6x2 + 12x + 8
We'll stop there, because estimate #2 is very close to the equation we're solving.
So, add (x + 2) to both sides of the problem, which leaves us with x3 + 6x2 + 12x + 8 = x + 2
y3 = y
Thus, x = -1,-2,-3
