The correct Answer is:
To solve the problem, we need to analyze both statements regarding the conditions under which a quadratic equation has real roots. ### Step-by-Step Solution: 1. **Understanding the Quadratic Equation**: The general form of a quadratic equation is given by: \[ ax^2 + bx + c = 0 \] where \(a\), \(b\), and \(c\) are real numbers. 2. **Condition for Real Roots**: A quadratic equation has real roots if its discriminant \(D\) is non-negative. The discriminant is given by: \[ D = b^2 - 4ac \] Therefore, for the quadratic equation to have real roots, we need: \[ b^2 - 4ac \geq 0 \] 3. **Analyzing Statement 1**: The first statement claims that the quadratic equation has real roots if: \[ (a + c)^2 > b^2 \] We can expand this: \[ a^2 + 2ac + c^2 > b^2 \] This does not necessarily imply that \(b^2 - 4ac \geq 0\). In fact, it is possible for \((a + c)^2 > b^2\) to hold while \(b^2 - 4ac < 0\). Therefore, Statement 1 is **incorrect**. 4. **Analyzing Statement 2**: The second statement claims that the quadratic equation has real roots if: \[ b^2 - 4ac \geq 0 \] This is the standard condition for a quadratic equation to have real roots. Thus, Statement 2 is **correct**. 5. **Conclusion**: - Statement 1 is false. - Statement 2 is true. ### Final Answer: - Statement 1: False - Statement 2: True
