General quadratic formula

Answer 1

Answer:

In other words, the quadratic formula is simply just ax^2+bx+c = 0 in terms of x. So the roots of ax^2+bx+c = 0 would just be the quadratic equation, which is: (-b+-√b^2-4ac) / 2a. Hope this helped!

Completing the square

1. Put the equation into the form ax 2 + bx = – c.
2. Make sure that a = 1 (if a ≠ 1, multiply through the equation by. before proceeding).
3. Using the value of b from this new equation, add. ...
4. Find the square root of both sides of the equation.
5. Solve the resulting equation.

Answer 2

In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.
