(3x^4-7x^3+2x^2-x+1)(x-2)

OpenStudy (anonymous):

please i need help

OpenStudy (anonymous):

the whole problem

OpenStudy (abb0t):

What are you being asked to do here first of all.

OpenStudy (anonymous):

synthetic division

OpenStudy (abb0t):

Ok, let's start with this is how it should look: |dw:1369680989199:dw|

OpenStudy (anonymous):

ok

OpenStudy (abb0t):

Now, for this, you must first start by dividing \(3x^4\) by \(x\) so, if you get \(\huge \frac{3x^4}{x}\) you get \(3x^3\) That is your first term.

OpenStudy (anonymous):

how do i do that

OpenStudy (abb0t):

|dw:1369681103863:dw|

OpenStudy (abb0t):

Now, multiply \(\large 3x^3\) by \(-2\)

OpenStudy (anonymous):

and where did the 3x^3 come from

OpenStudy (abb0t):

|dw:1369681163690:dw|

OpenStudy (anonymous):

and please go a litte slower

OpenStudy (abb0t):

\(3x^3\) came from when you divided by x! Remember :) because you have \(\large x-2\)

OpenStudy (abb0t):

You took: |dw:1369681269072:dw|
