Question

3x^3 + 2x^2 -40x=0 resolver equacion

Answer 1

...

$3 {x}^{3} + 2 {x}^{2} - 40x = 0 \\ x( {3x}^{2} + 2x - 40) = 0 \\ x = 0 \: \: \: o \: \: \: {3x}^{2} + 2x - 40 = 0 \\ x = 0 \: \: \: o \: \: \: (x + 4)(3x - 10) = 0 \\ x = 0 \: \: \: o \: \: \: x + 4 = 0 \: \: \: o \: \: \: 3x - 10 = 0 \\ x = 0 \: \: \: o \: \: \: x = - 4 \: \: \: o \: \: \: x = \frac{10}{3}$
