I need to write a polynomial in SIMPLEST FORM having roots 2,2 and 4. I have to gt rid of the parentheses by multiplying everything out.Did I do it correctly? Also, someone said yes yesterday , but I'm wondering if it is suppose to have anything else done to itit seems way too easy the way I did it.
(x2)(x+2)(x4)original problem
1.x^2 + 2x2x=x^24)
2. (x^24)(x4)
3. x^34x^24x+16=0

Reiny,
Everything is done ok
You wrote it as a polynomial equation by setting it equal to zero
If you just want the polynomial, it would be
x^34x^24x+16
