Question:
Make the given changes in the indicated examples of this section and then factor.
In Example 8, change the 8 to 36.
Data from Example 8
When factoring 2x2 + 6x − 8, first note the common factor of 2. This leads to 2x2 + 6x − 8 = 2(x2 + 3x − 4)
Now, notice that x2 + 3x − 4 is also factorable. Therefore, 2x2 + 6x − 8 = 2(x + 4)(x − 1)
