If the roots of the equation are equal, then a, b, c are in
For the following two (02) items: Consider the equation abx^{2}+bcx+ca=cax^{2}+abx+bc
- A. AP
- B. GP
- C. HP ✓
- D. None of the above
Correct Answer: C. HP
Explanation
From the previous question, we found that \frac{2}{b} = \frac{1}{a} + \frac{1}{c}. This is the standard condition for three quantities a, b, c to be in Harmonic Progression (HP).
