Question

математика, помогите решить неравенство!!!

Answer 1

3x^3 - 14x^2 + 13x + 6 = 0

3x^3 - 6x^2 - 8x^2 + 16x - 3x + 6 = 0

3x^2(x - 2) - 8x(x - 2) - 3(x - 2) = 0

(x-2)(3x^2 -8x - 3) = 0

(x - 2)(3x^2 - 9x + x - 3)=0

(x -2)( 3x(x-3) + (x-3)) = 0

(x-2) ( x - 3)( 3x + 1) =0

x=2

x=3

x=-1/3
