Question

Представьтев виде произведения.

Answer 1

6x^2 - 11x - 30 = 0 
D = 121 + 4*30 *6 = 841 = 29^2
x1 = (11 + 29)/12 = 40/12 = 10/3 
x2 = (11 - 29)/12 = - 18/12 = - 3/2

6(x - 10/3) (x + 3/2) = (6x - 20)(x + 3/2)

Answer 2

6x^2-11x-30=6(x-40/6)(x+3)=6(x-40/12)(x+3/2)=(6x-20)(x+3/2)
D=(-11)^2-4*6*(-30)=121+720=841
x1=(11+29)/12 = 40/12
x2=(11-29)/12 =-18/12=-3/2

Ответ: 6x^2-11x-30=(6x-20)(x+3/2)
