Answer 2

Types of Equation Roots

The types of roots an equation can have depend on the discriminant (\(D\)) of the quadratic equation \(ax^2 + bx + c = 0\). The discriminant is given by the formula \(D = b^2 - 4ac\).

1. Real and Distinct Roots: - When \(D > 0\), the equation has two real and distinct roots. - Example: If \(D > 0\), then the roots are real and distinct. For instance, if \(a = 4\), \(b = -3\), and \(c = 1\), then \(D = 16\), which is greater than 0, indicating two real and distinct roots.

2. Real and Equal Roots: - When \(D = 0\), the equation has two real and equal roots. - Example: If \(D = 0\), then the roots are real and equal. For instance, if \(log_3x = t\), and the discriminant \(D = 16\), then the roots are real and equal, such as \(t_1 = 7\) and \(t_2 = 3\).

3. Complex Roots: - When \(D < 0\), the equation has complex roots. - Example: If \(D < 0\), then the roots are complex. This means that the roots will involve imaginary numbers. For instance, if \(D < 0\), then the roots are complex.

In summary, the types of roots of a quadratic equation are determined by the discriminant \(D\), which is calculated using the formula \(D = b^2 - 4ac\). Depending on the value of \(D\), the equation can have real and distinct roots, real and equal roots, or complex roots.
