Question

Find the difference.

14x - (x2 + 8x) =

Answer 1

my best answer is 4x

Answer 2

in the parenthesis you add both numbers which is 10x, then you subtract 14x from 10x which will give you 4x :)

Answer 3

\[14x-(x^{2}+8x)=\]\[14x-x^{2}-8x=\]\[-x^{2}-6x.\]

Answer 4

well can you tell me how you got that? hmm ok i see were you get the anwser but tbh im still lost @-@

Answer 5

\[-x^2-6x\]

Answer 6

look at my first post :)

Answer 7

can you use this as an exampel to show me ???
(6x3 + 18x2) - 3x2 =

Answer 8

oh mines wrong, i did't see the x being squared lol take their answers ^.^

Answer 9

\[(6x^3 + 18x^2) - 3x^2 =\]\[6x^3 + \color{red} { 18x^2 } \color{red} { - 3x^2 } =\]\[6x^3 + \color{red} { 15x^2 } =\]\[6x^3 + \color{black} { 15x^2 } \]

Answer 10

ok i have to try that ! im still lost but i see what you guys are goiing kinda thanks!!!

Answer 11

(16x3 + 2x2) - 4x3 = ima try this one can you tell me if im right??

Answer 12

sure, go ahead :)

Answer 13

oh and the two 3 and two 2s are expomets

Answer 14

yes... so do you want to do it, or should I ?

Answer 15

i got 13x^3+2x^2??? is that right???

Answer 16

close, but it would be 12x^3, b/c 16-4=12, not 13.

Answer 17

ohh haha simpel mistake

Answer 18

yes, but I am sure that you are capable of doing this math .

Answer 19

thank you!! you helped alot!!
i have one more question tho... what do you do it there is a neagtive on the outside of a parinthasy like this equation? 7x - (25x2 + 12x) =

Answer 20

\[7x - (25x^2 + 12x) =\]\[7x - 25x^2 - 12x \]
see what I am doing in this step ?
Now....
\[\color{black} { 7x } - 25x^2 \color{black} { - 12x } \]
\[\color{red} { 7x } - 25x^2 \color{red} { - 12x } \]
\[\color{red} { 7x-12x } - 25x^2\]
\[\color{red} { -5x } - 25x^2\]
\[ - 25x^2\color{black} { -5x }\]

Answer 21

so basicaly the () dont need to be there?

Answer 22

well, when you have

-(a+b) we simplify it into -a-b

Answer 23

ohh ok i kinda understand
