x equals negative 2 plus or minus 2 I
x equals negative 2 plus or minus 4 I
x equals negative 4 plus or minus 2 I
x equals negative 4 plus or minus 4 I

Answer 1

hey! what way do you know of to solve this?

Answer 2

this is a quadratic, you can factor if you wish. it is the easiest way

Answer 3

x^2 + 4x + 8 = 0
But that cannot factor so we need to use the quadratic equation:
ax^2 + bx + c = 0 is what you have
quadratic formula:
(-b +- sqrt(b^2 - 4ac))/2a
Plug in your numbers and you will get two values for x.
