Multiplying Under the Radical

When multiplying under the radical, the expression can be represented as follows: - For the expression ax^2 + bx + c = 0, where a, b, and c are constants, the quadratic formula is used to find the roots of the equation. - The quadratic formula is given by x = (-b ± √(b^2 - 4ac)) / (2a).

Example Calculation

Let's consider an example to illustrate the process of multiplying under the radical: Given the quadratic equation ax^2 + bx + c = 0, with a = 5, b = 8, and c = 4, we can calculate the roots using the quadratic formula: - Discriminant (D) = b^2 - 4ac - D = 8^2 - 4*5*4 - D = 64 - 80 - D = -16 Since the discriminant is negative, the roots will be complex numbers.

Conclusion

Multiplying under the radical is an essential step in solving quadratic equations using the quadratic formula. It helps determine the nature of the roots based on the discriminant value.
