Solve -2x squared minus 16x minus 44

x=-4

Step-by-step explanation:

I would immediately reduce this by div. every term by -2:

x^2 + 8x + 22 = 0

Next, I'd "complete the square:"

x^2 + 8x    + (4)^2  - (4)^2 + 22 = 0

  (x + 4)^2  - 16 + 22 = 0, so that (x+4)^2 + 4 = 0.

Then sqrt(   (x+4)^2  = sqrt(

 x+4      = plus or minus i*2

 x          = -4 plus or minus i*2   (answer)

2(x^2-8x-22)

Step-by-step explanation:

factor 2 out of 2x^2-16x-44
