Instead assuming the expression is equal to an unknown y will be your best analytical guide for future advanced math classes including calculus. If the base of the parabola is above the x axis then, then y will never equal zero so bad bad bad assumption. Calculus is your best analytical tool. So the base of the parabola is located at 2. Only now can you conclude there are two points on y where the parabola touches the x-axis. The expression you have given is not an equation does not equal something , so it cannot be solved. I am going to assume that the expression is supposed to equal zero, and then solve that equation.

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, 1 , 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.

For using the factorisation method, the quadratic equation should be in descending order. It is already given in descending order. Similarly, all the terms in the left-hand side of the equation and there is no term in the right hand side of the equation. So, we can start the process for factoring the quadratic equation to solve it. The trinomial in the quadratic expression is expanded as a quadrinomial. There is a factor in every two terms commonly in the quadrinomial.
