....... S...............S + 12.................{Thats 4 over S + 12} Ignore the dots - just for spacing

Somehow = this below don't know how

40( 4 + S ) { Thats 40 ( 4 + S) all over S (S + 12) }
S ( S + 12)

Thank you.

Please, read the whole question before asking. This is a serious question.

Thank you.

Some examples:

1) x^2 - 3x^2 + 4x -12 = 0 can be solved so:
(x-3)(x^2+4) = 0

2) x^4 + ax^3+ bx^2 + cx + m^2 = 0, m= c/a can be solved so x+m/x = z

3) ax^5 + bx^4 + cx^3 + ax^2 + bx + c = 0 can be solved so: (x^3 + 1)(ax^2 + bx +c) = 0

Do you know other particular cases?

1=1
(5-4)^2=(3-4)^2
taking square root in both sides
5-4=3-4
(ading 4 on both sides)
3=5 !!!!!!!

(how can 3 equal 5)
