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.

Conclusion : Trinomial can not be factored. 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.
