Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

Solve by completing the square. Round.
x² -4x = 5

• 11 and -7

• 1 and 3

• 1.73 and -1.73

• 5 and -1

If there are no real solutions, the discriminant is

• zero

• a postive number

• a negative number

• a perfect square

If the discriminant equals 0, then the quadratic has:

• Real Solution

• Real Solutions

• Half a Solution

• No Real Solution

If the discriminant is positive, then the quadratic has:

• Real Solution

• Real Solutions

• Half a Solution

• No Real Solution

Multiply using the 'FOIL' method.

( 3x + 5 ) ( 2x + 3 )

• 6x² + 19x

• 6x² + 15

• 6x² + 19x + 8

• 6x² + 19x + 15
