Question

Simplify the equation x= -4 plus or minus the square root of -16 all over 2

Answer 1

x = -2+2i
or
x = -2-2i

Answer 2

`x = \frac{ - 4 \frac{ + }{} √( - 16) }{2} \\ \\ x = ( - 4)/(2) \frac{ + }{} ( √( - 16) )/(2) \\ \\ x = ( - 4)/(2) \frac{ + }{} ( √(16) √( - 1) )/(2) \\ \\ x = ( - 4)/(2) \frac{ + }{} (4i)/(2) \\ \\ x = - 2 \frac{ + }{} 2i`

x = – 2 + 2i , x = – 2 – 2i
