Question

Factor expression: 2X^(3/2)+6X^(1/2)-4X^(-1/2)

Answer 1

\[2x ^{\frac{ 3 }{ 2 }} + 6x ^{\frac{ 1 }{ 2 }} - 4x ^{\frac{ -1 }{ 2 }}\]

Answer 2

?

Answer 3

yes!

Answer 4

2x3=6
2x2=4
2x1=2
ok?

Answer 5

yup

Answer 6

so the factor is:
\[2x ^{\frac{ 1 }{ 2 }}(1+3-2^{-1})\]

Answer 7

wait , in the bracket, isn't it (x+3-....)

Answer 8

because we factor out x^1/2 from X^3/2

Answer 9

wait I think I made mistake...

Answer 10

It will be:

Answer 11

\[2x ^{\frac{ 1 }{ 2 }}(x ^{3}+3-2^{-1})\]

Answer 12

ok?got it?

Answer 13

why is it X^3?

Answer 14

3/2 - 1/2 = 1

Answer 15

shouldn't it be just x

Answer 16

x^1 = x

Answer 17

you are quite right sorry,sorry,sorry...so please write it.

Answer 18

but i dont know about the last one ...

Answer 19

1+1/2 = 3/2

Answer 20

4x^(-1/2) factor out 2x^1/2, leaves what?

Answer 21

you are right ;)

Answer 22

leaves 2^-1?

Answer 23

wait 'm confused :D let me doing it...

Answer 24

or 2X^-1

Answer 25

its ok

Answer 26

ok i think it's like......\[2x ^{1/2} (x+3-\frac{ 2 }{ x })\]

Answer 27

because 2/x = \[2X ^{-1}\]

Answer 28

well i'm guessing......

Answer 29

true :)

Answer 30

ok cool
