Quadratic Equation can be defined as a polynomial equation of a second degree, which implies that it includes at least one term that is squared. ; Its general form is given by, ; a, b and c are real numbers while a ≠ 0. Its shape is a parabola that opens upwards or downwards depending upon the value of “a”. ; Its solution is the point where the equation is satisfied.

Solving these two linear equations will give us the roots for the quadratic equation: x= · x= · To distinguish between the roots, write the x as: x · x · It is important to note that not all quadratic equations can be factored. In such cases, we need to use another method, such as the quadratic formula, to solve them. Related terms: Factor – a number or expression that divides another number or expression evenly, with no remainder. When multiplying two numbers or expressions, we get a ...
1 · Understand the definition of factoring when applied to single numbers. Factoring is conceptually simple, but, in practice, can prove to be challenging when applied to complex equations. Because of this, it's easiest to approach the concept of factoring by starting with simple numbers, then move on to simple equations before finally proceeding to more advanced applications. A given number's factors are the numbers that multiply to give that number. For example, the factors of 12 are 1, 12, 2, 6, 3 and 4, because 1 × 12, 2 × 6, and 3 × 4 ...
