In Example 9(a), change the coefficient of the first term from 20 to 5 and then factor Data from Example 9(a) In factoring 20x 2 45, note a common factor of 5 in each term Therefore, 20x 2 45 5(4x 2 9) However, the factor 4x 2 9 itself is the difference of squares Therefore, 20x 2 45 is completely ...

To change the coefficient of the first term from 20 to 5 we need to factor out the greatest common ...

In Example 9(a), change the coefficient of the first term from 20 to 5 and then factor.

Question:

In Example 9(a), change the coefficient of the first term from 20 to 5 and then factor.

Data from Example 9(a)

In factoring 20x² − 45, note a common factor of 5 in each term. Therefore, 20x² − 45 = 5(4x² − 9). However, the factor 4x² − 9 itself is the difference of squares. Therefore, 20x² − 45 is completely factored as 20x ² − 45 = 5(4x² − 9) = 5(2x + 3)(2x − 3)
