A quadratic equation is an equation that can be written as ax ² + bx + c where a ≠ 0. For Example: Solve x2 + 3x – 4 = 0. A quadratic equation has two roots and the roots depend on the discriminant. Example 1: Solve [latex]{x^2} + 4x – 12 = 0[/latex] using the Quadratic Formula. If it doesn't, factor an x out and use the quadratic formula to solve the remaining quadratic equation. , for x^2=49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Could anyone please shed some light? I get the exact same answer for the positive root and the negative root as well. A solution to this equation is also called a root of an equation. Equations which are reducible to quadratic ; Parabola finding vertex and X intercepts ; Quadratic Inequalities ; Solving quadratic equations by completing the square ; Solving quadratic equations using the quadratic formula ; Solving quadratic equations by factoring ; Quadratic equations by completing the square Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. Example 1 Solve x2 − 2x − 3 = 0 by factoring. Enter the equation you want to solve using the quadratic formula. cdd ankdf itlif fmmoxa wwhbalywp fpr vjbhd zdlvnu lyyga wufsar
