How do you factor a quadratic equation easily?
Identities for Factoring Quadratics
- Step 1: Divide both the sides of quadratic equation ax2 + bx + c = 0 by a.
- Step 2: Subtract c/a from both the sides of quadratic equation x2 + (b/a) x + c/a = 0.
- Step 3: Add the square of (b/2a) to both the sides of quadratic equation x2 + (b/a) x = -c/a.

What are the 4 methods of solving quadratic equations?
The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Can you solve every quadratic equation by factoring?
No. Every quadratic equation has two solutions and can be factorized, but as level of difficulty rises, splitting may not be easy and one may tend to use quadratic formula.

What does ax2 BX c mean?
The graph of a quadratic equation in two variables (y = ax2 + bx + c ) is called a parabola. We say that the first parabola opens upwards (is a U shape) and the second parabola opens downwards (is an upside down U shape). In order to graph a parabola we need to find its intercepts, vertex, and which way it opens.
What is the vertex of ax2 BX c?
For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
