Hint: Factor completely (Look for GCF first)

• 2(3x+5)²

• 2(3x-5)²

• 2(3x-5)(3x-5)

• 2(3x-25)(3x+25)

• (x-12)(x+2)

• (x+6)(x+4)

• (x-6)(x-4)

Hint: degree = highest exponent

Leading coefficient = number in front of the variable

• 3x⁴-2x²+4x-7

• 4+x-4x²+5x³

• 4x⁴-3x³+2x²

• 2x+x²+4x³

Which property was used to get to the second line?

• Associative property

• Commutative property

• Distributive property

• Zero property

Hint: cross-multiply to solve & put ( ) around the expression (x+10)

• -6

• 5

• 10

• 30
