WISCON WONDER!

-4+-isqrt3

x^2+8x=-19

Solve:

divide both sides by x: x+8=-19/x

Simplify: x-19/x=-8

Simplify: (x^2-19)/x=-8

(here is the funny part) Simplify: x^2-19=-8x

and we are back to where we started

x^2 + 8x = -19

x^2 + 8x + 19 = 0

x = (-b±√(b^2 - 4ac)) / 2a

but here,we don't found any number called a,b or c. So,this is a unsolvable equation.

x have no legal values in real number.

Solved.

SORRY GUYS, I FIXED THE EQUATION
