Week 5 – Factoring Expressions

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

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

=( $x^2$ – x) $^2$ + 5 ( $x^2$ – x) $^2$ – 24

= $a^2$ + 5 $a$ – 24

=(a – 3) (a + 8)

=( $x^2$ – x – 3) ( $x^2$ – x + 8)

=(x + 3) (x – 1) (x + 2) (x + 4)
