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. The method I am going to use is called completing the square. Completing the square is a valuable tool to use, because any binomial equation can be solved with it. Even though you could find the answer to this problem without it, I wanted to give you a chance to learn how to use it. Get a free answer to a quick problem. Most questions answered within 4 hours.

Move the constant term to the right: Add '-4' to each side of the equation. Why learn this. Other Ways to Solve Quadratic equations.

If it's not what You are looking for type in the equation solver your own equation and let us solve it. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. Take half its coefficient 4. Square it Add ' Move all terms containing x to the left, all other terms to the right.

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. Now, the zero product property can be used to solve the quadratic equation by making each linear expression in one variable equals to zero. A free math education service for students to learn every math concept easily, for teachers to teach mathematics understandably and for mathematicians to share their maths researching projects.

Conclusion : Trinomial can not be factored. Our parabola opens up and accordingly has a lowest point AKA absolute minimum.

Order of Operations. Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work. Solution - Quadratic equations. That is, if the parabola has indeed two real solutions. Least Common Multiple. Examples Quadratic equation. Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. Other Ways to Solve Quadratic equations. Each parabola has a vertical line of symmetry that passes through its vertex. The equation is now solved. Solve for a Variable. For this reason we want to be able to find the coordinates of the vertex. Examples Quadratic equation.

That is, if the parabola has indeed two real solutions. This step makes the left hand side of the equation a perfect square. Other Ways to Solve Quadratic equations. Step by step solution : Step 1 : Trying to factor by splitting the middle term 1. Steps Using Factoring By Grouping. We know this even before plotting "y" because the coefficient of the first term, 1 , is positive greater than zero. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. That is, if the parabola has indeed two real solutions. Prime Factorization. Systems of Equations. Observation : No two such factors can be found!! How did we do?
