Difference of Two Squares Pattern

Example 1: Factor a Difference of Two Squares m 2 – 25 9y p x

Example 1: Factor a Difference of Two Squares r 2 – 100 ¼ p m x

Perfect Square Trinomials

Example 2: Factor a Perfect Square Trinomial m m p p + 25

Example 3: Factor Out a Common Constant 5u 2 – 40u m 2 – 24m + 36

Checkpoint: Factor the Expression x x p 2 – 24p x x + 9 5x 2 – 10x + 5

Checkpoint: Factor the Expression 8y u 2 – 36u + 27

Example 4: Solve a Quadratic Equation 9p p = -25 x 2 – 6x = -9

Example 4: Solve a Quadratic Equation a = 12 2y 2 = 40y - 200
