For the Quadratic Formula to work you must have your equation arranged in the form quadratic 0Also the 2a in the denominator of the Formula is underneath everything above not just the square rootAnd its a 2a under there not just a plain 2Make sure that you are careful not to drop the square root or the plusminus in the middle of your calculations or I can guarantee that. In math we define a quadratic equation as an equation of degree 2 meaning that the highest exponent of this function is 2. Quadratic formula and examples A quadratic equation is any equation that can be written as a x 2 b x c 0 for some numbers a b and c where a is nonzero.
Quadratic equations have at most two real solutions as in the example above.
Put in a b and c. Quadratic Equations Solve Using the Quadratic Formula x2 2x 3 0 x 2 2 x - 3 0 Use the quadratic formula to find the solutions. X 6 36 20 10. In a quadratic equation the variable x is an unknown value for which we need to find the solution.
