Solve x2 - 5x + 6 = 0.
- A x = 2 or 3
- B x = 1 or 6
- C x = 5 or 1
- D x = -2 or -3
The roots of x2 = 16 are:
- A 4 and -4
- B -4 only
- C 8
- D 4 only
The quadratic formula gives x equal to:
- A (b plus or minus 2ac) / 4
- B -b / 2a only
- C (-b plus or minus the square root of (b2 - 4ac)) / 2a
- D (-b plus or minus the square root of (b2 + 4ac)) / a
Solve x2 + 2x - 8 = 0.
- A x = 1 or -8
- B x = 2 or -4
- C x = -2 or 4
- D x = 8 or -1
Which of these is a quadratic equation?
- A x2 + 2x + 1 = 0
- B 2x + 3 = 0
- C 1/x = 2
- D x3 = 8
Solve 2x2 - 8 = 0.
- A x = 4
- B x = 8
- C x = 2 or -2
- D x = 0
