Question

What polynomial has roots of -6, 1, and 4 ?

Answer 1

(x+6) * (x-1) * (x-4)

Answer 2

(x+6) * (x-1) = (x^2 + 5x - 6)

(x^2 + 5x - 6) * (x-4) = (x^3 +5x^2 -6x - 4x^2 - 20x +24)


(x^3 +5x^2 -6x - 4x^2 - 20x +24) reduces to

x^3 +x^2 - 26x +24

Answer 3

Wow! Thank you soo much! :))

Answer 4

you're welcome!

Answer 5

do you understand where i got (x+6) * (x-1) * (x-4) from?

Answer 6

yes, from the roots of the polynomial in the question.
