Question

I hate finding roots!

Answer 1

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

x3 - 3x2 - 22x + 24

x3 - x2 - 26x - 24

x3 + x2 - 26x + 24

x3 + 3x2 + 14x - 24

Answer 2

I'd appreciate any help at all...

Answer 3

simple ^.^
if a polynomial is to have a root, say, r, then it must have a factor (x-r)

for example, say, I want a polynomial with roots 2 and -3, then it should be
(x-2)(x+3) [note here that x+3 is the same as x - (-3)]

Anyway, this is equal to x^2 + x - 6

you get the idea? great :)

Answer 4

Oh, it's opposite of the factor! Okay, thank you so much!! :)) @PeterPan

Answer 5

answer?

Answer 6

I got x3 - 3x2 - 22x + 24! (A)

Answer 7

Because the factors are (x-1) (x+4) and (x-6)

Answer 8

nice ^.^
