Answer 1

Explain, in your own words, the step-by-step process to simplifying the expression below. Include the simplified answer in your explanation.

(6x2 − 5) − (3x2 + x + 7)

Answer 2

What I put: To simplify the expression (6x^2 − 5) − (3x^2 + x + 7), we can use two methods, the horizontal method and the vertical method. Here, let's use vertical method in this case, to me it is easier. The first step is to remove the parentheses by distributing the invisible "ones" before each set. So, (6x^2 − 5) − (3x^2 + x + 7) would become 1(6x^2 − 5) − 1(3x^2 + x + 7). This will then become 6x^2 − 5 − 3x^2 + x + 7. The next step is to sort the terms. One way to do this is to make a table. The table should have a column for each degree. *The largest degree in this example is 2. We must have a column for the x terms and a column for the constants. *The purpose of using a table is to align like terms vertically. We need to sort each term from the expression into the table. Oh, and let's not forget, we need to copy the sign in front of each of the terms! Then, our final step would be to combine like terms by adding down each column. So, in the x terms column we would have 6x^2, − 3x^2, and + x. In the constants column we would have - 5, and + 7. Now, we need to figure out the quantity. We do this by starting out with the x terms column. 6x^2 − 3x^2 + x = 3x^2 + x. Then we go to the constants column. - 5 + 7 = 2. So, (6x^2 − 5) − (3x^2 + x + 7) simplified would be 3x^2 + x + 2.

Answer 3

Do you have any option with you? :)

Answer 4

no :( wish I did >.>

Answer 5

in the question is that x^2 or x2??
i mean power or multiply?

Answer 6

LOL. Okay :D I'll help :)

Answer 7

aww thanks xoya ^O^

Answer 8

the x next to the -7? :) its just x :P

Answer 9

@xoya is my Cousin,@charlotte123 Don't hit her with your coconuts xD

Answer 10

@uri :O XD

Answer 11

@uri okay I wont ^-^ but its not like I was planning too, shes too nice ^-^

Answer 12

(6x2 − 5) − (3x2 + x + 7)
I am asking its (6 multiply by 2) or (6 power 2)??

Answer 13

oh my bad I forgot to put the ^ >.> the equation would be (6x^2 − 5) − (3x^2 + x + 7) :)

Answer 14

I already solved the problem, but the things is, I dont know if my answer is right or not :(

Answer 15

Okay wait I'll solve and let you know :)

Answer 16

thanks xoya :D

Answer 17

Listen may i know your answer? :)

Answer 19

I'm getting 3x^2+x+2

Answer 20

yep thats my answer :D

Answer 21

Ahaan i don't think we will solve this this :(
Well the question is (6x2 − 5) − (3x2 + x + 7)
We will first remove the brackets

Answer 22

Hahaha okay cool :D

Answer 23

yep :)

Answer 24

@xoya did ya get the same answer? :D

Answer 25

I got 3x^2+x+2 and you? :)

Answer 26

@xoya thats exactly my answer :D thanks for the help xoya! :D

Answer 27

Your always welcome xD

Answer 28

(6x2 − 5) − (3x2 + x + 7) Pemdas if i am correct

Answer 29

I used the vertical method, since in my lesson it gives me 2 options, whether horizontal or vertical >.>

Answer 30

Well just figure them and this is going on graph correct?

Answer 31

@Notamathgenius I just need to simplify the polynomial thats all :)

Answer 32

I got 3x^2 + x + 2 for the answer but Im not sure if its right or not >.>

Answer 33

Oh then do it
it's not hard
All you need to know is PEMDAS. That is the order of operations, or order of all the different applications you can do to an expression. Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.

Youd start out by multiplying inside each radical.
(12-5) - (6+x+7)

Then youd add everything up in each separate parenthesis.
(7)-(13 +x) *note you cant add x to the integers, since its a variable.

Next distribute the negative to the whole second term. [you can drop the parenthesis now]

7-13-x

And finish it all up and you get

6-x

Answer 34

@Notamathgenius thanks for the help ^-^
