User: What are all the real zeros of y = (x - 12)3 - 10?

Weegy: (x - y + 1) - (x + y - 1)

= 2 - 2y


User: -x3 + 5x2 - 11x + 55 = 0

Weegy: Find the roots of the polynomial equation. -x3 + 5x2 - 11x + 55 = 0 - - - I graphed it; x = 5 is a root. - - - - - - Use Synthetic division to find the 2 other roots: 5)....-1....5....-11....55 ......-1...0.....-11...|..0 - - - Quotient: -x^2 - 11 [ = 0 - - x = +sqrt(11), or x = -sqrt(11), or x = 5 ]

-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.

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)
