Question 1056414
.
X^2+4x+8=0
Can you find the solutions and then express them in the form a+bi?
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Simply apply the quadratic formula:


{{{x[1,2]}}} = {{{(-4 +- sqrt(4^2 - 4*1*8))/2}}} = {{{(-4 +- sqrt(-16))/2}}} = {{{(-4 +- 4i)/2}}} = -2 +/- 2i.


{{{x[1]}}} = -2 + 2i,  {{{x[2]}}} = -2 - 2i.

Solved.
