Question

Solve –3x2 – 4x – 4 = 0
x= 2 +_ 4i SQRT 2 / 3
x= 2+_ 2i SQRT 2 / 3
x= -2 +_ 2i SQRT 2 / 3
x= -2+_ 4i SQRT 2 / 3

Answer 1

I would first pull a -1 out it and then divide to leave it all positive.. make sense?

Answer 2

so it would be choice a or b?

Answer 3

c

Answer 4

opps... this is where I start: (-1){(3x^2)+4x+4} = 0

Answer 5

then: (3x^2)+4x+4 = 0

Answer 6

now with quadratic: -4 +-root(-32) all over 6

Answer 7

then you get to... -4 +- (i)root(32) all over 6

Answer 8

-4+-(i)root(4*4*3) all over 6

Answer 9

-4+-(4i)root(2) all over 6

Answer 10

-2+-(2i)root(2) all over 3

Answer 11

awesome thanks
