The middle term is, -2x its coefficient is When a product of two or more terms equals zero, then at least one of the terms must be zero. Earlier we factored this polynomial by splitting the middle term. Our parabola opens up and accordingly has a lowest point AKA absolute minimum. We know this even before plotting "y" because the coefficient of the first term, 3 , is positive greater than zero. Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts roots or solutions of the parabola. That is, if the parabola has indeed two real solutions. Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

Solve for a Variable. Greatest Common Factor. Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work. The middle term is, -2x its coefficient is Linear Equations. Solve Equations. Least Common Multiple. This step makes the left hand side of the equation a perfect square. This is achieved by dividing both sides of the equation by 3. Our parabola opens up and accordingly has a lowest point AKA absolute minimum. Steps for Completing the Square. Each parabola has a vertical line of symmetry that passes through its vertex.

Solve for a Variable. Quadratic equations such as this one can be solved by completing the square. In our case the x coordinate is 0. The factors r and s are the solutions to the quadratic equation. Noah G Oct 15, The definition of when a graph crosses the x-axis is the "x-intercept". Solve Practice Play. To find a and b, set up a system to be solved. Factor out common term 3x-1 by using distributive property. Solving a Single Variable Equation : 3. Then reduce the fraction to lowest terms if possible. Steps Using the Quadratic Formula. This is achieved by dividing both sides of the equation by 3. Since ab is negative, a and b have the opposite signs.
