Choose correct answer on basis of statements given below:
I. If the roots of the quadratic equation ax2 + bx + c = 0 are the negative reciprocal of each other, then a + c = 0.
II. A quadratic equation can have at most two roots.
III. If α and β are roots of x2– 22x + 105 = 0, then α + β = 22 and α - β = 8?
- I and II is true and III is false
- I and III are true and II is false
- II and III are true and I is False
- I, II and III all are true
