Given the xeros 0, 2, 1 + i, 1 - i, write the polynomial

I have no idea

how did you get x - 1 - i?

so the other zero is x = 1 - i, so x - (1 - i) = x - 1 + i? how do you multiply it?

i got it
thanks

Halley's Comet orbits the sun every 76 years. The comet travels in an elliptical path, with the sun at one of the foci. At the closest point, or perihelion, the distance of the comet to the sun is 8.8 x 10^7 km. At the furthest point, or aphelion, the distance of the comet from the sun is 5.3 x 10^9...

Thank you.

For this one, use "r=2" for the river current, so the equation is 16/(j-2) + 16/(j+2) = 6.

My ? is on useing the intermediate value thm for polynomial functions. I dont understand how it works. Here is my Problem. If f(x)=x^3-5x^2+7x-9, use the intermediate value theorem for polynomial functions to prove that there is a real number a such that f(a)=100. Help?

So I can use f(6)=69 and f(7)=138 to say that f(a)=100 for 6<a<7?
