Solution for (x-3)(x+2)=3x+28/3 equation:


x in (-oo:+oo)

(x-3)*(x+2) = 3*x+28/3 // - 3*x+28/3

(x-3)*(x+2)-(3*x)-(28/3) = 0

(x-3)*(x+2)-3*x-28/3 = 0

(3*(x-3)*(x+2))/3+(-3*3*x)/3-28/3 = 0

3*(x-3)*(x+2)-3*3*x-28 = 0

3*x^2-12*x-28-18 = 0

3*x^2-12*x-46 = 0

3*x^2-12*x-46 = 0

3*x^2-12*x-46 = 0

DELTA = (-12)^2-(-46*3*4)

DELTA = 696

DELTA > 0

x = (696^(1/2)+12)/(2*3) or x = (12-696^(1/2))/(2*3)

x = (2*174^(1/2)+12)/6 or x = (12-2*174^(1/2))/6

(x-((12-2*174^(1/2))/6))*(x-((2*174^(1/2)+12)/6)) = 0

((x-((12-2*174^(1/2))/6))*(x-((2*174^(1/2)+12)/6)))/3 = 0

((x-((12-2*174^(1/2))/6))*(x-((2*174^(1/2)+12)/6)))/3 = 0 // * 3

(x-((12-2*174^(1/2))/6))*(x-((2*174^(1/2)+12)/6)) = 0

( x-((12-2*174^(1/2))/6) )

x-((12-2*174^(1/2))/6) = 0 // + (12-2*174^(1/2))/6

x = (12-2*174^(1/2))/6

( x-((2*174^(1/2)+12)/6) )

x-((2*174^(1/2)+12)/6) = 0 // + (2*174^(1/2)+12)/6

x = (2*174^(1/2)+12)/6

x in { (12-2*174^(1/2))/6, (2*174^(1/2)+12)/6 }
