Hai



<Puzzle>

Let x be a solution to the equation x² + x + 1 = 0.

x² = − x − 1 (Moving x + 1 to R.H.S.)

x = − 1 − 1 / x (Dividing x)

Note it is legal division as x ≠ 0 is given by provided equation

Substitute x = − 1 − 1 / x back in for x the original equation

x² + ( −1 − 1 / x ) + 1 = 0

x² = 1 / x (Simplify)

x³ = 1 (Multiplying x on both sides)

x = 1 (Solving the cube root)

Substitute x = 1 into the original equation:

(1)² + 1 + 1 = 0

3=0

the cube root of one has three complex roots!

you can't be naughty and just use 1 and disregard the other two, especially when 1 evidently isn't a root of the original quadratic!

Well you see depends on the maths, because just a touch of maths here and there is fine. And all those kids who are like I will never even need this!?? They're all being silly dills, but then sometimes it's a case of hmm actually though why do I need mathematics useful for civil engineering when I am in a chemical engineering course, and then I might fail my exam so we shall see and I'll reserve judgement on maths until the 12th December.
