I need help with number 4 please thank you !

D) -2, 3

Step-by-step explanation:

First, factor r^4-13r^2+36 to get  (r^2-2)(r^2-9)

Which, in simple terms, is  (r+2)(r-2)(r+3)(r-3).

You should now have  (r+2)(r-2)(r+3)(r-3) over r^3 + r^2 - 6r

Now, factor  r^3 + r^2 - 6r to get  r(r-2)(r+3)

Your equation should look like this:

Now, cancel out equal operations that lie both above and below the fraction line. So r-2 cancels out r-2 and r+3 cancels out r+3.

You now have

Subtract 2 from 2 to get zero and add 3 to -3 to get zero.

0 over any number is equal to zero, so the roots are -2 and 3.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
