Find the zeros of the problem: x^3 - 10x^2 + 25x = 0
I came out with the solution (0,5,5) but i think it might actually be (0,5,D.R.)
*(D.R. meaning double root)(^ meaning to the __ power)
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
x^3 - 10x^2 + 25x = 0
x(x^2 - 10x + 25) = 0
x(x - 5)(x - 5) = 0
x = 0 or x-5 = 0 or x-5 = 0
x = 0 or x = 5 or x = 5
So the solutions are x = 0 or x = 5 or x = 5
You can say that the unique roots are 0 and 5, where 0 is a single root and 5 is a double root.
