  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

What do you need to do ?

#

Partial frac decomp ?

#

Oooh okay

#

Did you find the poles of the fraction ?

#

Okay lol

#

I persevere and try solving the problem at hand.
That aside do you know how to partial frac decomp ?

#

take x common from the denom first

#

then factorise like a quadratic

#

do like something

#

except for Caesar's Theorem

#

uh

#

split the middle term?

#

nvm that won't work here

#

you'll have to do quadratic formula

#

DO IT

#

@frail tiger where exactly are you stuck?

#

Use Quadratic formular to find the factors of the denominator

#

GOOGLE IT THEN

#

Hey

#

Qudratic Formular:
$$
ax^2+bx+c=0 \implies x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}
$$

@frail tiger got it done?

#

Yes

#

Know you have to do the actual partial fraction decomposition

#

I guess they want you to find $A, \ B, \ C$ such that
$$
\frac{5x-3}{x^3+ 12x^2 + 6x} = \frac{A}{x} + \frac{B}{x-\sqrt{30}+6} + \frac{C}{x+\sqrt{30}+6}
$$

#

Note that
$$
x^3 + 12x^2 + 6x = x \cdot (x-\sqrt{30}+6) \cdot (x+\sqrt{30}+6)
$$
