How many solutions does this graph have?

• one
• two
• no solutions
• cannot be determined

Solve by graphing:

2x² + 17x + 21 = 0

• x= ^-21/₂ or x = -17

• x= ²/₃ or x = 16

• x=-7 or x = ^-3/₂

• x=15 or x = -³/₇

What are the solutions?

• 0 and 8
• -2 and -4
• 3 and -1
• 2 and 4

Solve with graphing:

2x² + 7x - 15 = 0

• -1.5 or 5

• No Solution

• -5 or 1.5

• 0.7 or 5

Solve the following quadratic equation...

x² + 7x + 12 = 0

• x = -2

  x = -6

• x = -3

  x = -4

• x = -1

  x = -12

• x = 2

  x = 6
