Last year in grade 10, we learned how to factor simple expression, but this week we added another step

ex

1.) Replace the complicated set of varibles with a simple varible (a)

2.) Factor the expression

3.) Once properly factoring substitue the varibles back in

=( – x) + 5 ( – x) – 24

= + 5 – 24

=(a – 3) (a + 8)

=( – x – 3) ( – x + 8)

=(x + 3) (x – 1) (x + 2) (x + 4)
