Question

What polynomial has roots of –5, –2, and 4 ?

Answer 1

to do this problem you go like this

(x+5) ( x+2) and (x-4)

Answer 2

x3 + x2 – 22x – 40 ?

Answer 3

(x+5) * ( x+2) *(x-4) expand by distributive property

Answer 4

–5, 2, and 4

(x+5)(x-2)(x-4)

= (x^2 + 3x - 10)(x-4)

= x^3 + 3x^2 - 10x - 4x^2 - 12x + 40

= x^3 - x^2 - 22x + 40

Answer 5

Awwwww thanks huneya. I was so close!

Answer 6

x^3 +3*x^2 -18*x -40

Answer 7

@huneya i think
(x+5)(x-2)(x-4)
is wrong

Answer 8

What polynomial has roots of –5, –2, and 4 ?
i is (x+5) * ( x+2) *(x-4)

is not (x+5)(x-2)(x-4)

-5, 2 and -4
