Question

(-4+√(-16-4*1*3))/(2*1) I need this done ASAP!!! Aaagghh

Answer 1

hmm use PEMDAS, what would you get in the radical?

Answer 2

Me and my family have no clue what to do! We tried PEMDAS but we cant figure it out and its for school so i need to get it in today :P

Answer 3

If you know, maybe you could walk me through it ?

Answer 4

grouped elements first
now inside them
multiplication first FROM LEFT TO RIGHT
sum/subtraction next, FROM LEFT TO RIGHT
\(\bf \cfrac{-4+\sqrt{-16-\color{red}{4\times 1\times 3}}}{2\times 1}\)

Answer 5

so... what does the multiplication gave you?

Answer 6

in the red or at the bottom? Im so sorry im so math dumb. Ugh.

Answer 7

the red part for now....lemme include the bottom
\(\bf \bf \cfrac{-4+\sqrt{-16-\color{red}{4\times 1\times 3}}}{ \color{red}{2\times 1}}
\)

Answer 8

okay so the top red is 12 and the bottom is 2

Answer 9

next the radical amounts then
\(\bf \cfrac{-4+\sqrt{-16-4\times 1\times 3}}{2\times 1}\implies\cfrac{-4+\sqrt{\color{red}{-16-12}}}{2}\)

Answer 10

4 and 3.4??

Answer 11

well,.... -16 -12 is ... no ... 3.4 :|

Answer 12

omg i thought something else lol sorry i mean -28
