Quadratic Equations Solving Quadratic Equations Completing the Square Solved Examples on Algebra Example 1: Solve the equation 5x – 6 = 3x – 8. Solution: Given, 5x – 6 = 3x – 8 Adding 6 on both sides, 5x – 6 + 6 = 3x – 8 + 6 ...
Apolynomialof the second degree is generally called a quadratic polynomial. In elementary algebra, the quadratic formula is the solution of the quadratic equation. There are other ways to solve the quadratic equation instead of using the quadratic formula, such as factoring, completing the square, ...
Notice what would have happened if we had not drawn this inference. We would have thought that since there is a quadratic equation, we will get multiple roots and hence we will not be able to find a unique value of x and hence statement 1 is not sufficient. And as a result, we would...

(Theorem 1.) A rational expression[2] in the coefficients of the general quadratic equation \[ ax^2 + bx + c = 0 \] cannot be a solution to this equation. Sketch of proof. Assume to the contrary that the rational expression \(x = f(a, b, c)\) is a solution. Assume that we...
The word Algebra is derived from an Arabic word, 'Al-jabr' which means the 'reunion of broken parts' and Algebra is considered as the science of restoring and balancing, according to the Persian mathematician, Al-Khwarizmi. Therefore, the meaning of Algebra is finding the unknown, or putting...
How To: Given a graph of a quadratic function, write the equation of the function in general form. Identify the horizontal shift of the parabola; this value is h. Identify the vertical shift of the parabola; this value is k. Substitute the values of the horizont...

This is a variation of the quadratic formula. Similar procedures appear as far back as Babylonia, and represented the state of algebra (and its close ties to astronomy) for more than 3,500 years, across many civilizations: Assyrians, in the 10th century B.C.; Chaldeans, in the seventh ...
