Question

Can someone please help me solve -3x2 - 4x - 4 = 0?

Answer 1

So far i got x=+4+/- sqrt-32 all over -6

Answer 2

I think the next part is to simplify the sqrt-32 which is 4isqrt2 right?

Answer 3

use the Quadratic Formula

x = \[\frac{ -b \pm \sqrt{ b ^{2}-4ac} }{ 2a }\]
and you will have two answers for x

Answer 4

think a = -3, b = -4, c = -4

Answer 5

i have used that and i get x=2+/-2i sqrt2/-3 for my answer which doesnt match my choices did I mess up somewhere?
