Factor and Solving Quadratics

Find the missing value "c" to create a perfect square trinomial:
x² – 8x  + ___ 

• -4

• 16

• 4

• 8

What should be added to both sides of the following equation to complete the square?
x² + 12x = 5

• 12

• 6

• 36

• 5

Factor
3a² + 4a + 1

• (7a-10)(a-8)

• Not factorable

• (3a+1)(a+1)

• (3a-1)(a-1)

Factor:

5x² - 28x + 32

• (3x-10)(x+6)

• (x-8)(5x-4)

• (5x-8)(x-4)

• (5x-8)(x+4)

Solve x² - 2x - 8 = 0 using the quadratic formula

• x = 2 , -3

• x = 4 , -2

• x = 2 , -4

• x = 3 , -2

• No Solution

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Factor: 49x² - 100

• (49x + 100)(x - 1)

• (7x - 10)(7x + 10)

• (49x - 10)(x + 10)

• (7x -10)(7x - 10)

Factor:   3x²- 6x - 24

• (3x - 8)(x + 3)

• (3x + 4)(x - 6)

• 3(x - 2)(x + 4)

• 3(x + 2)(x - 4)

7x² - 26x - 8 = 0

• x = -1 and x = -7/8

• x = 4 and x = -2/7

• x = -4 and x = 2/7

• x = 4 and x = -7/2

Solve
(x+3)²-5 = 9

• -3±√14

• 3±√14

• ±11

• ±5
