Chapter 1.5 - 1.7, 8.1 Test Review

Solve the equation by factoring:

x² + 13x + 40 = 0

• -8, 5

• -40, -1

• 5, 8

• -8, -5

Solve by factoring. (HINT: Factor GCF 1st)

• x = 3, x = -6

• x = 0, x = 2

• x = 2, x = 3

• x = -2, x = 1

12. Solve using any method.

(x - 2 )² -49 = 0

• 5, 9

• ^{-9, -5}

• 9, -5

• ^{9, -9}

Solve the following quadratic equation...

x² + 3x + 2 = 0

• x = -1

  x = -2

• x = 1

  x = 2

• x = -1

  x = 2

• x = 1

  x = -2

k² - 2k = 0

• k = 2 and 0

• k = -2 and 0

• k = 2

• k = 0

Solve by finding square roots and simplify completely:
 $2x^2=20$ 

•  $x=\pm10$  

•  $x=\sqrt{10}$  

•  $x=\pm\sqrt{10}$  

• No real solutions

Solve using the Quadratic Formula:
 $5x^2+3x-1=0$ 

•  $x=\frac{3\pm\sqrt{29}}{5}$  

•  $x=\frac{8}{5}\ or\ x=-\frac{2}{5}$  

•  $x=\frac{-3\pm\sqrt{29}}{10}$  

• No real solutions

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12
