Question

Explain how to find the values of a, b, and c, in a quadratic equation?

Answer 1

Given:

A quadratic equation with values (coefficients) as a, b and c

To Find:

Values of a, b and c

Solution:

Let the standard form of a quadratic equation be where and are constants and , and is called variable.

Example -

(i) Let be quadratic equation. Compare this equation with standard form and we can deduce that

(ii) Let be another quadratic equation. Here, because, the value is 0 for variable .
