Are you absolutely positive that those are the signs exactly as in the question? As far as I know, there isn't 2 numbers that add to -3 and multiply to -2, meaning you can't factor it

Simplify -14x^3/x^3- 5x^4 where x=?

ki77a [65]

Step-by-step explanation:

$\dfrac{-14x^3}{x^3-5x^4}\qquad\text{where}\ x^3-5x^4\neq0\\\\x^3-5x^4\neq0\qquad\text{distributive}\\\\x^3(1-5x)\neq0\iff x^3\neq0\ \wedge\ 1-5x\neq0\\\\x\neq0\ \wedge\ x\neq\dfrac{1}{5}\\\\\dfrac{-14x^3}{x^3(1-5x)}\qquad\text{cancel}\ x^3\\\\=\dfrac{-14}{1-5x}\qquad\text{where}\ x\neq\dfrac{1}{5}$

Suppose we want to choose 2 colors, without replacement from 3 colors red blue and green how many ways can this be done in the o

andre [41]

The two colors can be chosen in 3 different ways.

<h3>In how many ways can we choose two colors?</h3>

If we have a set of N elements, the number of different sets of K elements (such that the order of the K elements does not matter) is:

$C(N, K) = \frac{N!}{(N - K)!*K!}$

In this case, we have 3 colors, so N=3, and we want to choose 2, then K=2.

Replacing that we get:

$C(3, 2) = \frac{3!}{(3- 2)!*2!} = \frac{3*2*1}{1*2*1} = 3$

The two colors can be chosen in 3 different ways.
