Answer:
1 solution
Step-by-step explanation:
There is only one solution as it is not a quadratic
An expression for the value of 12 6+6
1. planes, a line
2. 4, plane
3. two, line
4. two, line
(i think four is wrong, tell me if it is)
This is a problem of Difference-of-squares. We know that for a difference of squares

the factorization is given by:

To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.
Applying distributive property:

Applying distributive property again:

Simplifying:
<em>The correct answer is C</em>
