Simplify; \(\frac{a}{b} - \frac{a}{a} - \frac{c}{b}\)
- A. \(\frac{a - b + c}{ab}\)
- B. \(\frac{ab - bc - ac}{ab}\)
- C. \(\frac{a^2 - b^2 + ac}{ab}\)
- D. \(\frac{a^2 - b^2 - ac}{ab}\)
Correct Answer: D. \(\frac{a^2 - b^2 - ac}{ab}\)
Explanation
\(\frac{a}{b} - \frac{b}{d} - \frac{c}{b}\)
\(\frac{a^2 - b^2- ac}{ab}\)
