This is a quadratic equation with coefficients a= -3, b= -4 and c= 5.  Thus, the discriminant  b^2-4ac is      (-4)^2 - 4(-3)(-4)  =  16-48 = 16(1-3) = 16(-2).

The solutions are
       -(-4) plus or minus sqrt(discriminant)
x = ---------------------------------------------------
                        2(-3)
          4 plus or minus sqrt(16[-2])
   = -----------------------------------------
                           -6
         4 plus or minus 4*i*sqrt[2]
   = ---------------------------------------
                            -6

This reduces to:
 
       -2  plus or minus i*2*sqrt[2]
x = --------------------------------------            (answers)

Answer:

no. i*i = -1

2i*3i=-6

now if they meant complex numbers the answer is still no

(2+4i)(2-4i) = 4-8i+8i-16 = -12
