Question

What is the quotient: (6x^3 + 23x^2 + 10x – 25) ÷ (2x + 5) ?  Would the remainder theorem work on this?

mathslover · Answer

no..... here you must apply "Long-division" method

mathslover · Answer

Remainder theorem is to calculate remainder ...

anonymous · Answer

oh okay! so how would i do the long division?

anonymous · Answer

it is 0

mathslover · Answer

divide as u usually do

anonymous · Answer

remainder = 0

mathslover · Answer

@85295james note that quotient can not be 0.. I hope you r talking about remainder

mathslover · Answer

good

anonymous · Answer

how would you usually divide? synthetically?

anonymous · Answer

lol

mathslover · Answer

@kakrazz try to do

parthkohli · Answer

Don't synthetically divide here.

anonymous · Answer

how would i synthetically divide this? I wouldnt know what to do with the 2x.. if it was (x-5), then i would but not 2x

parthkohli · Answer

Synthetic division works if and only if the divisor is in the form $x - k$ or $x + k$.

anonymous · Answer

yeah so how would i do this

anonymous · Answer

$$6x+4$$

parthkohli · Answer

Two ways:
1) long division.
2) take out your calculator and input your question.

anonymous · Answer

how would i use my calculator?

http://www.wolframalpha.com is is the good one =) i gave it to you like ten min ago lol

parthkohli · Answer

It depends on you: it's good to do long division yourself.

anonymous · Answer

OH okay, so i just did the math and i got 3x^2+4x-5

anonymous · Answer

save that link this time

anonymous · Answer

haha yes, i have that link open!
