**Complex Numbers in the Quadratic Formula Cool Math**

To use the quadratic formula, you must first put the equation into standard form. For example, 5=6x^2-25x becomes -6x^2+25x+5. Then, you look at the coefficients and constants, and assign the variables to them. For example:... The Quadratic Formula If the discriminant is positive--if b 2 -4 ac > 0 --then the quadratic equation has two solutions. If the discriminant is zero--if b 2 - 4 ac = 0 --then the quadratic equation has one solution.

Equations that can be rearranged to be a quadratic equation in standard form The standard form for a quadratic equation is ax 2 + bx + c = 0, a ≠ 0. We may however, be given a quadratic equation that is not in this form and so our first...13/01/2008 · If you are applying the quadratic formula, yes, "a" can be negative. But since you are looking for zeroes, you can change all the signs (and also divide out any common numeric factor) to make the arithmetic more tractable. Thus, y = -8(2x^2 -6x -1), and you can apply the formula to the internal quadratic.

- In case the number you get is negative, there will be 2 complex solutions. the solutions of a quadratic equation are often called roots. You can check if your calculation is right by going back to the original expression and substituting your answers instead of X.
- 13/01/2008 · If you are applying the quadratic formula, yes, "a" can be negative. But since you are looking for zeroes, you can change all the signs (and also divide out any common numeric factor) to make the arithmetic more tractable. Thus, y = -8(2x^2 -6x -1), and you can apply the formula to the internal quadratic.
- If a and (c - b^2/a) are both positive or are both negative the quadratic will be either always positive or negative. If they are not both then the quadratic will be be positive for some values and negative …
