x+1

-x^3-x^2

-3*x^2-7*x-4

3*x^2+3*x

-4*x-4

4*x+4

0

x^2-3*x-4 = 0

DELTA = (-3)^2-(-4*1*4)

DELTA = 25

DELTA > 0

x = (25^(1/2)+3)/(1*2) or x = (3-25^(1/2))/(1*2)

x = 4 or x = -1

x in { -1, 4, -1} 

(x+1)^2*(x-4) = 0

2/3*(x+1)^2*(x-4) = 0

( x+1 )

x+1 = 0 // - 1

x = -1

( x-4 )

x-4 = 0 // + 4

x = 4

x in { -1, -1, 4 }
