Factoring Part 2

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)

Factor completely.
3x² - 9x -120

• 3(x - 8)(x + 5)

• 3(x + 8)(x - 5)

• 3(3x + 8)(x - 5)

• 3(3x - 8)(x + 5)

Factor completely:
 3x² + 5x - 12

• (3x + 4)(x-3)
• (3x - 4)(x + 3)
• (3x + 3)(x -4)
• (3x - 3)(x + 4)

Factor completely: 2x²+22x+60

• (2x+10)(x+6)
• (x+5)(x+6)
• 2(x+1)(x+30)
• 2(x+5)(x+6)

What is the first step when factoring polynomials?

• Find the GCF

• List all the terms

• Make the X and fill in the top and bottom

• Multiply a and c

Factor Completely: 
3x² + 18x +15

• 3(x² + 6x + 5)

• (3x + 15)(x + 1)

• 3(x + 5)(x + 1)

• Prime

Factor Completely: 
2k²-14k-60
 

• 2(k-10)(k-3)

• Not Factorable

• 2(k-5)(k+9)

• 2(k-10)(k+3)

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)

Factor
x² + 9x - 36

• (x + 12)(x - 3)
• (x + 9)(x - 4)
• (x - 12)(x + 3)
• (x - 9)(x - 4)

Factor out the GCF:
10x³ - 15x

• x(10x² - 15)
• 5x(2x² - 3)
• 5(2x³ - 3x)
• 5x²(10x - 3)
