Help

Answer 1

Thank you anyway :)

Answer 2

this 4x^2 -16 is difference of two squares

do you know formula of this ?

Answer 3

2x^2 +10x +12 =

what can you factorizing out from these every terms ?

Answer 4

I figured it out I believe I ended up with 2x^4 + 3/ 1x^3 - 4

Answer 5

ok i like help you step by step

please answer my posted questions and will get sure the right answer

Answer 6

1x^2 + 5x + 6

Answer 7

fo 4x^2 -16 = 4(x^2 -4) = ?

x^2 -4 =

use a^2 -b^2 = (a-b)(a+b)

Answer 8

so there above wrote x^2 +5x +6 this has a 2 in front again ,yes ?

Answer 9

will be

2(x^2 +5x +6) = 2(x*x +(2x+3x) +2*3 =

you can factorizing completly

Answer 10

Kitty do you see it how ?

Answer 11

this x^2 +5x +6 = x*x +2x +3x +2*3 = x(x+2) +3(x+2) = ?

Answer 12

factorize out the (x+2) and will get = (x+2)(x+3)
but dont forgot the 2 from the front of these all

Answer 13

so this is clearly ?

Answer 14

what about this

fo 4x^2 -16 = 4(x^2 -4) = ?

x^2 -4 =

use a^2 -b^2 = (a-b)(a+b)

Answer 15

Kitty please collaborate bc. is opposite to OS rules to give directly right answers

Answer 16

just dm her the answer lol

Answer 17

@TheSmartOne

Answer 18

Sorry, was on the phone with my teacher

Answer 19

what grade you in?

Answer 20

ok. so please collaborate Kitty , wait

Answer 21

I am in 12th grade but this is a class from 11th grade I never finished

Answer 22

ohhhhhhhh

Answer 23

fo 4x^2 -16 = 4(x^2 -4) = ?

x^2 -4 =

use a^2 -b^2 = (a-b)(a+b)

Answer 24

Wouldn't you factor it so it would be
4x^2 - 16

Answer 25

so than you factorize out the 4 and factor it will can simplify more easy what will be possible

Answer 26

Kitty how you divide two fractions ?

Answer 27

Kitty you dont know it ?

Answer 28

multiplie the first by second inversed

Answer 29

sshayer your opinion about this ?

Answer 30

x + 3
----------
4x^2 - 16
----------------- = ?
2x - 4
-----------------
2x^2 + 10x + 12

Answer 31

x +3 2x^2 +10x + 12
----------- * ------------------- = ?
4x^2 - 16 2x -4

Answer 32

\[\frac{ x+3 }{ 4 x^2-16 }\times \frac{ 2x^2+10 x+12 }{ 2x-4 }=\frac{(x+3)2(x^2+5x+6) }{ 4(x^2-4)2(x-2) }\]

Answer 33

now cancel 2 and make factors and see if you can cancel any factor

Answer 34

but you can factorizing again completly the x^2 +5x +6 = ?

Answer 35

and x^2 -4 = (x-2)(x+2)

yes ?

Answer 36

sshayer ???

x^2 +5x + 6 = (---)(---) ???

Answer 37

\[x^2+2x+3x+6=x(x+2)+3(x+2)=(x+2)(x+3)\]

Answer 38

yes sure this is easy

Answer 39

Kitty do you understand these ?

Answer 40

I don't but my teacher is about to call to check my answers

Answer 41

\[=\frac{ \left( x+3 \right)\left( x+2 \right)\left( x+3 \right) }{ 4(x+2)(x-2)(x-2) }=\frac{ \left( x+3 \right)^2 }{ 4\left( x-2 \right)^2 }\]

Answer 42

Thank you guys so much I got a 4/5 on my test
I know I didn't really understand it but I appreciated the help

Answer 43

let me know where you don't understand.
