Final answer:

To find the roots of a quadratic equation, the quadratic formula is applied using the coefficients a, b, and c from the standard form of the equation, resulting in two potential solutions for x.

Step-by-step explanation:

The question requires us to use the quadratic formula to find the roots of a quadratic equation. The standard form of a quadratic equation is ax² + bx + c = 0. In this case, the quadratic formula is used, which is x = (-b ± √(b² - 4ac))/(2a). If we have, for example, the equation x² + 1.2 x 10⁻² x - 6.0 × 10⁻³ = 0, we can identify a, b, and c and plug these values into the quadratic formula. After simplification, we obtain two possible solutions for x.
