• A.

  (x - 5)(x + 19)

• B.

  (x - 8)(x + 3)

• C.

  (x - 3)(x + 8)

• D.

  (x - 19)(x + 5)

Find all the solutions for x when

x² + 9x - 36 = 0

• A.

  (x + 12)(x - 3)

• B.

  x = 12 and x = -3

• C.

  x = -12 and x = 3

• D.

  (x - 9)(x - 4)

The solutions of the quadratic equation
x²-5x+6=0 are

• x=1 or x=-6
• x=3 or x=2
• x=-3 or x= 2
• x=-1 or x=6

Solve the following quadratic equation...

x² + 13x + 36= 0

• x = -2

  x = -18

• x = -9

  x = -4

• x = -3

  x = -12

• x = -6

  x = -6

• -2.5

• -3

• 2

• 0

Solve for the values of x:
(x + 2)(x - 3) = 0

• { 2, 3 }
• { -2, -3 }
• { 2, 3 }
• { -2, 3 }

• A.

  x = 7 only

• B.

  x = 0 only

• C.

  x = 0 and 7

• D.

  There is no real answer for this equation.
