Learning Target 4.5: Solving Quadratic

Factor
81m² - 1 

• not factorable
• (m-9)(m+9)
• 9m(9m-1)
• (9m-1)(9m+1)

60m³ + 54m² - 6m

• (6m²+6m) (10m-1)

• (60m²-1) (m+1)

• 6m (10m-1) (m+1)

• PRIME (Not Factorable)

Solve by factoring:  2x²+ 7x + 6 = 0

• x= 3/2 and x = 2
• x = -3/2 and x = -2
• x = 6 and x = 7
• x = -6 and x = -7

What are the zeros for f(x)=0?

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2

Solve for the values of x:
(x + 2)(x - 3) = 0

• { 2, 3 }
• { -2, -3 }
• { 2, 3 }
• { -2, 3 }
