In algebra, a quadratic equation (from the Latin quadratus for “square”) is any equation having the form ax2+bx+c=0ax2+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers such that a is not equal to 0. If a = 0, then the equation is linear, not...
Example 2. c = 0. Solve this quadratic equation:ax² + bx = 0Solution. Since there is no constant term: c = 0, x is a common factor:x(ax + b) = 0. This implies: x = 0 or x = − ba .Those are the two roots.Problem 4. Find the roots of each quadratic....
