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>Answer:
Okay, so. What I'd do is this.
Then I'd combine like terms.
So:
Once you've got 6x, you subtract 6 from 180.
Now all that's left to do is divide each side by 6 to get x.
X should be 29.
Step-by-step explanation:
You know that adding the equations will give you 180 because you know they're supplementary.
