The mathematical principles applied to each Quadratic Equation in Standard Form include factorization or factoring, variation(correlation of variables), monomial rules, domain and range.

It really depends what you work in; if you work in science, or in engineering (applied science), you will need the quadratic equation - and a lot more advanced math as well. Examples that involve the quadratic equation are found in abundance in algebra textbooks; for example, an object in free fall.

I suggest you apply the quadratic formula (a = 2, b = -4, c = -1).

You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.

You can combine equivalent terms. You should strive to put the equation in the form ax2 + bx + c = 0. Once it is in this standard form, you can apply the quadratic formula, or some other method, to solve it.

To solve the equation x^2 + 7x - 80, you would get x = 6.105 and x = -13.105, I believe.

The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.

You put everything to the left side. For example, if you have a constant term on the right side, subtract it on both sides, so that you have an equation where the right-hand side IS zero. For example: 5x2 + 3x - 5 = 20 Subtract 20 from both sides: 5x2 + 3x - 25 = 0 Now you can apply the quadratic formula.

There are several methods for solving quadratic equations, although some apply only to specific quadratic equations of specific forms. The methods include:Use of the quadratic formulaCompleting the SquareFactoringIterative methodsguessing
