Question

simplify\[(\sqrt{-3}+4)(\sqrt{-3}-1)\]

Answer 1

im coming up with 3-1square root -3 +4square root-3-4 answer -3+4square root 3

Answer 2

so would it be just square root of 3

Answer 3

2i^2

Answer 4

nevermind, misread the Q

Answer 5

phemoo1 how did you come up with that i must have missed leaving a neg in root to pull out the i

Answer 6

\[(\sqrt{-3}-4)(\sqrt{-3}+1)\]right?

Answer 7

yes how did you write that on here would be a huge start and help alot

Answer 8

use the "equation" feature at the bottom of the little window you have
it won't work that well for the original post though, you need to learn the language LaTeX for that

I'll do it for you, but experiment with the equation button

Answer 9

i can do it on the button below but that doesnt post it the first time

Answer 10

yeah I know, that's why I did it for you
anyway, gotta FOIL it out\[(\sqrt{-3}-4)(\sqrt{-3}+1)=\sqrt{-3}\cdot\sqrt{-3}+\sqrt{-3}-4\sqrt{-3}-4(1)\]

Answer 11

which i did

Answer 12

whats \[\sqrt{?}\]

Answer 13

you mean how do you make the symbol?

Answer 14

3-1\[3-1\sqrt{?}\]

Answer 15

is that what you get for the simplification?
I am confused what you are writing

Answer 16

\[3-1 \sqrt}-3 +4\sqrt{-3-4\]

Answer 17

it would be like this if you want to do it the right way...

Answer 18

\[(\sqrt{-3}-4)(\sqrt{-3}+1)\.]

write this without the little dot at the end

Answer 19

I keep dropping that 4 :/

Answer 20

take out the dot and you get\[(\sqrt{-3}-4)(\sqrt{-3}+1)\]

Answer 21

when i foiled it i got \[3-1\sqrt{?}\]

Answer 22

forget it

Answer 23

what did you get after foil will tell you if i got same

Answer 24

after FOILing you get\[\sqrt{-3}\cdot\sqrt{-3}+(1)\sqrt{-3}-4\sqrt{-3}-4(1)\]

Answer 25

why -4

Answer 26

and 1 shouldnt it be -1 and +4
