Worksheet Worksheet 5

1.
Use the \(ac\) method to factor \(x^2 + 9x + 20\) using a complete presentation.
2.
Use the \(ac\) method to factor \(4x^2 - 4x - 3\) using a complete presentation.
3.
Factor \(x^2 + 10x + 16\) and \(x^2 - 10x + 16\text{,}\) then compare the results. What do you notice about the factorizations?
4.
Factor \(x^2 - 5x - 14\) and \(x^2 + 5x - 14\text{,}\) then compare the results. What do you notice about the factorizations?
