Question

The zero of linear polynomial \( ax + b \) is:

• A. \( \frac{a}{b} \)
• B. \( \frac{-a}{b} \)
• C. \( \frac{b}{a} \)
• D. \( \frac{-b}{a} \)

Hint:

For a linear equation of the form \( ax + b = 0 \), the zero is found by solving for \( x \), which gives \( x = \frac{-b}{a} \).

Answer 1

The Correct Option is D

Step 1: Understanding the zero of a polynomial
- To find the zero of the linear polynomial \( ax + b \), we set it equal to zero and solve for \( x \): \[ ax + b = 0 \] \[ ax = -b \] \[ x = \frac{-b}{a} \] Step 2: Conclusion
The zero of the polynomial \( ax + b \) is \( \frac{-b}{a} \), which is option \( (4) \).
