2.5 Factoring Trinomials (a=1) Math 2

Factor

x² + 9x - 36

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

Factor
k² - 2k - 24

• (k+4)(k-6)
• (k+4)(k+6)
• (k+6)(k-1)
• (k-4)(k+6)

Factor
a² - a - 12

• (a - 4)(a + 3)
• (a + 6)(a - 4)
• (a - 6)(a + 4)
• (a + 4)(a - 3)

Factor:

 8b + b² + 7

• (b + 4)(b + 3)
• (b + 6)(b + 1)
• (b + 7)(b +1)
• prime

Factor
x² +17x - 60

• (x - 20)(x + 3)
• (x + 12)(x - 5)
• (x - 12)(x + 5)
• (x + 20)(x - 3)

Factor:
x² + 7x - 30

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

Solve for the values of x:

(x - 5)(x - 1) = 0

• { 5, 1 }
• { 5, -1 }
• { -5, 1 }
• { -5, -1 }

Solve

(2x -8) (x + 5) = 0 

• x = 5, x = 8
• x= -4, x = 5
• x= 4, x = -5
• x= -5, x = -8

solve the polynomial equation

2x(x - 5) = 0

• x = 0, 5

• x = 0, - 5

• x = 5

• x = -5

Solve by factoring.
k² + 8k + 12 = 0

• -2, 2
• -2, 4
• -2, -6
• 2, 3
