Equal roots occur in a quadratic equation when the discriminant equals zero. This means both roots have the same value indicating the parabola touches the x-axis at exactly one point. For example x² + 4x + 4 = 0 has ...
The quadratic formula finds solutions (x-values) where ax² + bx + c = 0. For any quadratic equation the roots are x = [-b ± √(b² – 4ac)] / (2a) where b² – 4ac is called the discriminant and determines ...
A system of equations is a set of two or more equations with the same variables. The solution satisfies all equations simultaneously. Methods to solve include substitution elimination and graphing. Solutions can be unique infinite or no solution depending on ...
A pair of equations consists of two mathematical statements connected by conditions like “and” or “or” to find the values of variables. These equations can be linear quadratic or other types. Solving them involves finding solutions that satisfy both equations ...
