so we have that one of the solutions is 3 and we know that this is limited so the we get graph b

in a 30-60-90 triangle the legs of the 60^o triangle has legs 4 and 4sqrt3 so we have x=sqrt(2(4sqrt3)^2) since it is an 45-45-90 triangle and we simplify to get x=sqrt(2*48) so $x=\sqrt{96}=4\sqrt6$

x=−4+3i,−4−3i where i=sqrt-1

Oh the answer is there already? so that means that i'm right since I got the same answer

Your welcome

We can use the values of x, y, and z to find the discriminant.

I think it's -156
