Aplica la regla del aspa simple.
3x² + 2x - 8 = 0
3x - 4
x + 2
(3x - 4)(x + 2) = 0
Igualamos a cero.
3x - 4 = 0
3x = 4
x = 4/3
.............................................
x + 2 = 0
x = - 2
.............................................
CS{4/3; - 2}
(3x +6)(3x-4)
----------------- = (x+2)(3x-4) =0
3 * 1
(x+2)=0 (3x-4) = 0
x1 = -2 3x=4
x2 = 4/3
