Question

Solve −2x2 − 16x − 44 = 0. x equals negative 8 plus or minus I square root of 6 x equals negative 8 plus or minus 2i square root of 6 x equals negative 4 plus or minus i square root of 6 x equals negative 4 plus or minus 2i square root of 6

Answer 1

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(-4)
