Factoring Trinomials

What is ALWAYS the first step when factoring?

• Find magic numbers

• Write a, b, and c

• Difference of squares

• Look for the GCF

Factor:
 x² - 15x + 50

• (x - 10)(x - 15)

• (x - 10)(x - 5)

• (x - 25)²

• (x - 5)²

• (n-7)(n+4)

• (n+7)(n-9)

• (n-3)(n-10)

• (n+7)(n+9)

Factor: 3v² - 4v-7

• (3v-7)(v+1)

• 3(v-7)(v-1)

• (3v+1)(v-9)

• (3v+1)(v-10)

4n² -17n-15

• (n-10)(6n+1)

• (4n-5)(n-3)

• (n-5)(4n-3)

• (n-5)(4n+3)

Factor
r² -16r + 60

• (r - 15)(r + 4)
• (r - 6)(r + 10)
• (r - 6)(r - 10)
• (r +30)(r - 2)
