Question

For f(x) = x3 – 3x2, determine the number and type of possible complex zeros, and find the zeros to the nearest tenth.

Answer 1

two real roots; 6, 0
three real roots; 3, 0, 0
three real roots; 3, 1, 2
four real roots; 3, 0, 1, –1

Answer 2

let f(x)=0

x^3 - 3x²=0

take out the highest factor

x²(x-3)=0

can you do it now?

Answer 3

I don' tknow how to find the root from that. :\

Answer 4

you have two equations

x²=0

x-3=0

work out x in both cases

Answer 5

oh. okay. i get it. thanks.
