Plug these numbers into the formula. Simplify to get your answers. Advisories: The "2a" in the denominator of the Formula is underneath everything above, not just the square root. And it's a "2a" under there, not just a plain "2". Make sure that you are careful not to drop the ...
Do you see b2 − 4ac in the formula above? It is called the Discriminant, because it can "discriminate" between the possible types of answer:when b2 − 4ac is positive, we get two Real solutions when it is zero we get just ONE real solution (both answers are the same) when it ...
Use the quadratic formula to find the real solutions, if any, of the equation. x^2 + 6x - 1 = 0. Use the quadratic formula to find the real solutions, if any, of the equation. x^2 + 2x - 18 = 0 Use the quadratic formula to find the rea...

The general form of a quadratic function is given as: f(x) = ax2 + bx + c, where a, b, and c are real numbers with a ≠ 0. The roots of the quadratic function f(x) can be calculated using the formula of the quadratic function which is:...
We can also use the quadratic formula:We get two answers x+ and x− (one is for the "+" case, and the other is for the "−" case in the "±") that gets us this factoring:a(x − x+)(x − x−)Example: what are the roots of 6x2 + 5x − 6 ? Substitute a=6...
