    What are the real or imaginary solutions of the polynomial equation? 27x3 + 125 = 0

    27x^3+125=0 is the equation?

    27x^3+125=0.... so factor the left side (3x+5)(9x^2-15x+25)=0 Now split each side (3x+5)=0 (9x^2-15x+25)=0 And solve each one separably. For the first one: (3x+5)=0 ... subtract 5 and then divide by 3 You get x=-5/3 Now solve the other part using the quadratic equation.
