so
and you rationalize denominator by multiplying numerator and denominatr by so that gives--
Your answer is
x^2 + 2x + 8
First, we'll try using the AC method.
(Because the degree of the quadratic is 2, there are two solutions.)
We cannot split the term using the AC method.
We'll instead use the quadratic formula.
Plug in values.
(-2 +/- √4 - 32)/2
(-2 +/- √-28)/2
(-2 +/- i√28)/2
(-2 +/- 2i√7)/2
(-1 +/- i√7)
<h3>x = (-1 + i√7)</h3><h3>x = (-1 - i√7)</h3><h3>The two values of x are found.</h3>
