Answer choices?

Answer 2

x3 + 2x2 − 3x − 6

x3 − 2x2 − 3x + 6

x3 + 3x2 − 5x − 15

Answer 3

Thank you.

Answer 4

how do I solve it?

Answer 5

You have to use the FOIL method, are you familiar with it?

Answer 6

yes

Answer 7

Alright, what is your first step

Answer 8

I don't know

Answer 9

how do i do that with the square roots?

Answer 10

First, multiply first terms of each binomial:
q*q=q2

Answer 11

Here, I'll just give you the answer shhh x^3-2x^2-3x+6.

Answer 12

there aren't any binomials in this, how did you get that answer?

Answer 13

hello, can you please explain how to solve this?

Answer 14

Which of the following is a polynomial with roots negative square root of 3 , square root of 3, and 2?


\[-\sqrt(3), \sqrt(3), 2\]
are the roots
So
\[(x+\sqrt(3))( x-\sqrt(3))(x-2)\]

Answer 15

And then expand from there

Answer 16

\[(x+\sqrt(3))(x-\sqrt(3)) = x^2 + xsqrt(3)-xsqrt(3) -3 = x^2-3\]
and then now
\[(x^2-3)(x-2)\]

Answer 17

You good now?
