00:00:00.000 --> 00:00:06.119
Here is the problem: 4/(x squared minus 4) equals 1/(x minus 2).

2
00:00:06.569 --> 00:00:10.633
A quadratic equation in x: solve with the quadratic formula.

3
00:00:11.433 --> 00:00:12.907
Start with the equation.

4
00:00:13.357 --> 00:00:32.630
Multiply both sides by x ^ 3 -2 cdot x ^ 2 -4 cdot x plus 8 to clear the fractions. This is only valid where x ^ 3 minus 2 times x ^ 2 minus 4 times x plus 8 not equal to 0, so any value that makes it zero is excluded at the end.

5
00:00:33.080 --> 00:00:36.122
Move every term to one side to get standard form.

6
00:00:36.572 --> 00:00:37.977
Compute the discriminant.

7
00:00:38.777 --> 00:00:42.597
delta equals 0, so there is one repeated real root.

8
00:00:43.047 --> 00:00:44.858
Apply the quadratic formula.

9
00:00:45.308 --> 00:00:46.388
Factored form.

10
00:00:46.838 --> 00:00:52.643
Remove extraneous roots. x equals 2 makes a denominator zero and is rejected.

11
00:00:53.443 --> 00:00:55.417
So the answer is No solution.

12
00:00:55.867 --> 00:01:02.020
The quadratic formula gives every solution of ax squared plus bx plus c equals 0.
