Answer 1

\[3+\sqrt{z-1 }= \sqrt{z+14}\]

Answer 2

z=2

but the way I got there.... I don't think you would know...

Answer 3

\[3+\sqrt{z-11} = \sqrt{z+4}\]

Answer 4

i got 2.

Answer 5

i have to square both terms then use foil

Answer 6

im just making sure they are correct cause i always make mistakes

Answer 7

i have no clue how i posted the other problem

Answer 8

\[3+\sqrt{z-11} = \sqrt{z+4}\]
\[z=12\]


I've been using using phasor form and de moivre's

Answer 9

oh yea i dont know what that is lol

Answer 10

basically, it's a quicker route then trying to get everything to FOIL correctly... but it involves switching to sin and cos ... which can be a bit more difficult if you're not used to it.
