Solving Quadratic Inequality Using the Method of Parabolas

To solve the quadratic inequality 5x^2 + 10x + b ≥ 0 using the method of parabolas, we can follow these steps:

1. Find the Discriminant (D) - The discriminant (D) of a quadratic equation in the form ax^2 + bx + c is given by the formula: D = b^2 - 4ac.

2. Determine the Nature of the Parabola - If the discriminant (D) is greater than 0, the parabola opens upwards and has two distinct real roots. - If the discriminant (D) is equal to 0, the parabola touches the x-axis at one point. - If the discriminant (D) is less than 0, the parabola does not intersect the x-axis.

3. Identify the Solutions - Based on the nature of the parabola, we can determine the range of values for which the inequality holds true.

4. Substitute the Coefficients - In this case, the coefficients are: a = 5, b = 10, and c = b.

5. Apply the Method of Parabolas - By analyzing the nature of the parabola, we can determine the range of values for which the given inequality holds true.
