Solving Quadratics

Solve:  $2x^2-x-15=0$  

•  $x=-\frac{5}{2}$  and  $x=3$  

•  $x=\frac{5}{2}$  and  $x=-3$  

•  $x=\frac{5}{2}$  and  $x=3$  

•  $x=-\frac{5}{2}$  and  $x=-3$  

Solve in any method

• A
• B
• C
• D

• x= 0 or x = 3

• x = 0 or x = -3

• x = 3

• x = -3

• F
• G
• H
• I

Solve using square roots:

x² - 49 = 0

• x = -7, x = 7

• x = -7

• x = 7

• x = -7, x = 1

Solve using Slip-n-Slide

2x² - 3x - 2 = 0

• x = 1, x = -1

• x = -1/2, x = 2

• x = 1/2, x = 2

• x = 1/2, x = 1

Solve

3x² - 192 = 0

• -32 or 32
