-x^3 + 5x^2 - 11x + 55 = 0

- x^2(x - 5) - 11(x - 5) = 0

(x - 5)(-x^2 - 11) = 0

(x - 5)(x^2 + 11) = 0

x - 5 = 0 or x^2 + 11 = 0 (which is not possible)

so, x = 5

The solution for the equation -x^3 + 5x^2 - 11x + 55 = 0 is x = 5.

- x^2(x - 5) - 11(x - 5) = 0

(x - 5)(-x^2 - 11) = 0

(x - 5)(x^2 + 11) = 0

x - 5 = 0 or x^2 + 11 = 0 (which is not possible)

so, x = 5

The solution for the equation -x^3 + 5x^2 - 11x + 55 = 0 is x = 5.

What polynomial has a graph that passes through the given points?
(-2, 2) (-1, -1) (1, 5) (3, 67) **Weegy:** The step by step solution to this problem can be viewed here: **User:** Divide -3x3 - 2x2 - x - 2 by x – 2. **Weegy:** Divide -3x3 - 2x2 - x - 2 by x ? 2. is x=1.
**User:** Find the real solutions of the equation by graphing x2 + 2x + 2 = 0 **User:** What is a quartic function with only the two real zeros given?
x = -4 and x = -1 **Weegy:** -1 + -4= -5 **User:** Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind? (More)
