Factor out the greatest common factor <br>-5x^2 - 5x^3 - 15x^4

vaieri [72.5K]

Our answer is $-5x^{2} (3x^{2} +x+1)$

Our greatest common factor, or GCF, is $-5x^{2}$ , so when we factor is out, our divide each term by $-5x^{2}$ , we get our answer. To check this, we can multiply the $-5x^{2}$ back across the parenthesis and see if we get the same result as our initial question.

Hope this helped! :))

Answer/Step-by-step explanation:

The problem replaces the x with the appropriate input. It is asking for you to find the correct output (y). Looking at the graph, when the point hits -1 on the x value, the value for y is 3. So, the correct output is 3.
