Use long division to find the quotient below. (5x5 + 90x2 - 135x) (x + 3) A. 5x4 + 15x3 - 45x2 - 45x B. 5x4 + 5x3 - 25x2 - 45x C. 5x4 - 5x3 + 25x2 - 45x D. 5x4 - 15x3 + 45x2 - 45x

hello

OpenStudy (anonymous):

it me

OpenStudy (anonymous):

hi it me

OpenStudy (anonymous):

You can use synthetic division instead and still get the correct answer

OpenStudy (anonymous):

teach me syntheic division

OpenStudy (anonymous):

just use the number in one bracket to time the other

OpenStudy (anonymous):

explain the answer to me

OpenStudy (mathmale):

could you possibly use or indicate the division symbol, please? You are to use long division, according to the problem statement.

OpenStudy (anonymous):

wut

OpenStudy (anotherarabgurl):

i suggest using mathpapa it gives you the answer and it shows you the steps

OpenStudy (anotherarabgurl):

http://www.mathpapa.com/algebra-calculator.html

OpenStudy (anonymous):

the site didnt work

OpenStudy (anotherarabgurl):

okay wait

OpenStudy (anonymous):

what is that 0.o

OpenStudy (mathmale):

Set up long division, please. Your divisor is (x+3) and your dividend is (5x5 + 90x2 - 135x). I need to see what you already know about this topic.

OpenStudy (mathmale):

@AnotherArabGurl : This problem involves division, NOT multiplication.

OpenStudy (anonymous):

dont u do 5x5 by all of the numbers in (x+3)

OpenStudy (anonymous):

then 90x2 by all the things in (x+3)?

OpenStudy (anonymous):

or somethin like that

OpenStudy (mathmale):

No multiplication here. You were told to use long division. I asked you to show the "divide" operator, but you have not yet done that. That's why the problem looks like one in multiplication; that is not the case.

OpenStudy (mathmale):

Find a way to include the division symbol: (5x5 + 90x2 - 135x) (x + 3) You could use the Draw utility if you wish.

OpenStudy (anonymous):

(5x5 + 90x2 - 135x) (x + 3)

OpenStudy (anonymous):

/

OpenStudy (mathmale):

(5x5 + 90x2 - 135x) / (x + 3)

OpenStudy (anonymous):

yes

OpenStudy (mathmale):

this is division. Set up long division, please. The (x+3) comes first. Then what?

OpenStudy (anotherarabgurl):

Mathmale can you help me plz

OpenStudy (anonymous):

(x+3) \ (5x5)

OpenStudy (anonymous):

?

OpenStudy (mathmale):

What do you want me to do? Haven't you seen long division before?

OpenStudy (anonymous):

explain more

OpenStudy (mathmale):

(x+3) is your divisor; 5x^5 + 90x^2-135x is your dividend. What does a problem in long division look like? _____ 2 / 6 equals 3; 2 is the divisor, 6 is the dividend. Set this up for the problem at hand: (x+3) is your divisor; 5x^5 + 90x^2-135x is your dividend.

OpenStudy (anonymous):

im sorry ): i still dont understand

OpenStudy (mathmale):

Have you not studied long division before? No examples, no practice problems?

OpenStudy (anonymous):

can u show me what long division looks like?

OpenStudy (mathmale):

You haven't answered my question. I'v e asked you the same question twice, and I showed you the example _______ 2/ 6 = 3.

OpenStudy (anonymous):

(x+3)

OpenStudy (anonymous):

is on the top?

OpenStudy (mathmale):

|dw:1457642822670:dw|

OpenStudy (anonymous):

i was supposed to know that?

OpenStudy (anonymous):

i was supposed to type all that out? in this little chat box

OpenStudy (mathmale):

|dw:1457643029464:dw|

OpenStudy (anonymous):
