Further, the new expression after splitting the x term has four terms in the quadratic expression. The process of factorization of a quadratic equation includes the first step of splitting the x term, such that the product of the coefficients of the x-term is equal to the constant term. Here the quadratic expression is of the second degree and is split into two simple linear expressions. The aim of factorization is the break down the expression of higher degrees into expressions of lower degrees. The factorizing of a quadratic expression is helpful for splitting it into two simpler expressions, which on multiplying, gives back the original quadratic expression. Mentioned below are a few examples: ExpressionsĮxpand the term x(x 2 + x - 3) and simplify Move an expression by -1 if the equation starts with a negative value.Writing any expression or equation into a quadratic standard form, we need to follow these three methods.
The terms in a quadratic expression are usually written with the power of 2 first, the power of 1 next, and the number in the end.However, if the numbers are negative the term will also be negative. The standard form is written in a positive form. In a quadratic expression, it is not necessary that all the terms are positive.Variable b or c in the standard form can be 0 but 'a' cannot. If a = 0 then x 2 will be multiplied by zero and therefore, it would not be a quadratic expression anymore. The variable 'a' in a quadratic expression raised to the power of 2 cannot be zero.In the alphabets, the letters, in the end, are written for variables whereas the letters, in the beginning, are used for numbers. The expression is usually written in terms of x, y, z, or w.Listed below are a few important properties to keep in mind while identifying quadratic expressions.
