The distance covered by an object is governed by the expression x3 + 3x2 + 2x. If the time taken to cover this distance is given by x + 1, what is the expression that governs the speed of the object?

x2+2x

x2+2x−1x+1

x+2

x2+1x+1

what a weird way to ask you to find 
$$\frac{3^3+3x^2+2x}{x+1}$$

anonymous · Answer

$$\frac{x^3+3x^2+2x}{x+1}$$actually

anonymous · Answer

im at total loss I have no idea what this question is asking for ive been outta school 8 months

anonymous · Answer

they made a silly word problem is all
distance divided by time is rate, so really they are asking you to divide one polynomial by another

anonymous · Answer

i wrote above exactly what it is  asking in math rather than in words, namely it is asking for $$\frac{x^3+3x^2+2x}{x+1}$$

anonymous · Answer

I didn't learn anything about polynomials yet I don't know which one it would be

anonymous · Answer

my teach thinks the third one

anonymous · Answer

do you know how to divide polynomials?

anonymous · Answer

your teacher "thinks" it is the third one??!!

anonymous · Answer

(hint, it is definitely not the third one!)

anonymous · Answer

my teachers a history teacher and im stuck doing math all day n I don't know how to divide them at all

anonymous · Answer

this topic was new to me 5 mins ago

anonymous · Answer

it is almost impossible for me to show you how to divide polynomials here
you can read about it if you like 
on the other hand, if you just want the answer, once you know that the question is really a division problem, and since you are on the computer, use the computer to solve it

anonymous · Answer

i will send a link with the answer 
you can see what i wrote, and where the answer is

anonymous · Answer

look at "alternate forms" you will find $x(x+2)$ which is not an answer choice, but it is the same as 
$$x^2+2x$$

that website is there a fee to get calcs on it like that

anonymous · Answer

you can pay if you want special features, but no, it is free
also very smart, so be careful how you use it

anonymous · Answer

notice the use of parentheses when i made the fractions

anonymous · Answer

noted I appreciate your help

anonymous · Answer

no problem
