The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.

## How do you write equations in C++?

The formula can be translated into the C++ code as: payment = P * R / (1 – pow(1 + R, -N)); Notice that the expression 1 + R is the base and the expression -N is the exponent.

## Which of the following is a quadratic equation?

## How do you find all roots of a quadratic equation?

For a quadratic equation ax2 + bx + c = 0,
1. The roots are calculated using the formula, x = (-b ± √ (b² – 4ac) )/2a.
2. Discriminant is, D = b2 – 4ac. If D > 0, then the equation has two real and distinct roots. If D < 0, the equation has two complex roots. …
3. Sum of the roots = -b/a.
4. Product of the roots = c/a.
