Is there any way to do this instead of long division? It's

https://en.wikipedia.org/wiki/Synthetic_division

if there wasn't a coefficient of 2 in the divisor you could do synthetic division

No, synthetic division works when any poly is being divided by a linear factor.

long division is best division

yes, just stop being an idiot.

just write 2x^3 + 7x^2 + 2x+9 = (2x+3)(whatever) and use ur brain.

I want to get smarter. How do I start on solving that

>>8657522
It's just division, and simple at that. Literally just type 'algebraic long division' into youtube and watch a 5min tutorial. Voila.

>>8656378

you can't always rely on this technique, sadly

>>8657301
So divide everything else by 2 first, then do synthetic division.

just put it into wolfram alpha or something

>>8656376

use a computer

unless you have an arbitrary constraint imposed by a teacher

>>8657536
implying

>>8658481
idk what he was implying but, if this technique doesn't work there's most likely another method that you can do to solve the problem. Or you may have to do something like partial fractions before you do this and whatnot. The method's perfectly fine.

>doing this lel shit on an exam when u need to compute division ASAP cuz rest of problem is hardest part

>>8656376
do grid method like a retarded 16 year old
