So, Erik's solution strategy would work.
Now, let us discuss about Caleb's solution strategy:
Multiply i.e.
=
So, the equation becomes:
Comparing this equation to standard quadratic equation:
a = 3, b = -10, c = -8
So, this can be solved using the quadratic formula.
The answer is same from both the approaches.
So, the correct answer is:
C) Both
