If in a quadratic equation `ax ^(2) + bx + c =0,` value of a is zero then it become a `"________"` equation.

Answer

To solve the question, we need to analyze what happens to the quadratic equation when the coefficient of \(x^2\) (which is \(a\)) is set to zero.

### Step-by-step Solution:

1. **Identify the Quadratic Equation**:
The standard form of a quadratic equation is given by:
\[ ax^2 + bx + c = 0 \]
where \(a\), \(b\), and \(c\) are constants.

2. **Set the Value of \(a\) to Zero**:
According to the question, we set \(a = 0\). This changes the equation to:
\[ 0 \cdot x^2 + bx + c = 0 \]
which simplifies to:
\[ bx + c = 0 \]

3. **Recognize the New Form of the Equation**:
The equation \(bx + c = 0\) is a first-degree equation in \(x\). It no longer contains the \(x^2\) term because \(a\) is zero.

4. **Conclusion**:
Since the equation is now of the first degree, it is classified as a linear equation.

### Final Answer:
If the value of \(a\) is zero in the quadratic equation \(ax^2 + bx + c = 0\), it becomes a **linear equation**.
