SOLUTION: Ok so we've got to write a polynomial function. r1=4, r2=5, and r3=6 (x-4)(x-5)(x-6)=0 (x^2)-5x-4x+20=0 ((x^2)-9x+20)(x-6) I'm stuck here. I hope it all makes sense.

Question 211171: Ok so we've got to write a polynomial function.
r1=4, r2=5, and r3=6

You're off to a great start. I'll start where you left off.

Start with the given equation.

Rearrange the terms.

Expand. Note:

Distribute

Multiply

Combine like terms.

So

This means that the polynomial with the roots , , and is
