A quadratic equation (from the Latin quadratus for “square“) is any equation that can be rearranged in standard form as: \[ax^2+bx+c=0\] where \(x\) represents an unknown, and \(a\), \(b\), and \(c\) represent known numbers, where \(a\neq 0\). If \(a=0\), then the equation is linear, not quadratic, as there is no \(ax^2\) term. The numbers \(a\), \(b\), and […]
In mathematics, equations are equalities between monomials or polynomials, for which the purpose is to search for the numerical value of one or more literal variables, called unknown (for example \(x\)), which make the equality true. This value is called the solution or root of the equation. An equation is written as two expressions, connected by an equals sign (“=“)
Notable products between binomials Notable products are used in algebra for the literal calculation of the product between binomials. They are said to be notable because the product of some particular polynomials always reaches the same result. For this reason, it is possible to avoid, for these particular polynomials, the carrying out of all the
