Example 1: Factor a Difference of Two Squaresm2 – 25
9y2 - 16
p2 - 625
x2 - 36
Example 1: Factor a Difference of Two Squaresr2 – 100
¼ p2 - 81
9m2 - 64
16x2 - 25
Perfect Square Trinomials
Example 2: Factor a Perfect Square Trinomialm2 + 16m + 64 9p2 + 30p + 25
Example 3: Factor Out a Common Constant5u2 – 40u + 80 4m2 – 24m + 36
Checkpoint: Factor the Expressionx2 + 10x + 25
9p2 – 24p + 16
4x2 + 12x + 9
5x2 – 10x + 5
Checkpoint: Factor the Expression8y2 - 18 12u2 – 36u + 27
Example 4: Solve a Quadratic Equation9p2 + 30p = -25 x2 – 6x = -9
Example 4: Solve a Quadratic Equationa2 - 4 = 12 2y2 = 40y - 200
P. 252 – 253# 20 – 64 EVEN
