10: Quadratic Equations - Mathematics LibreTextsQuadratic equations are equations of the form ax²+bx+c=0 , where a≠0 . They differ from linear equations by including a term with the variable raised to the second power. We use different methods to solve quadratic equations than linear equations, because just adding, subtracting, multiplying, and dividing terms will not isolate the variable ...
