**How Do You Solve a Quadratic Equation by Completing the**

Completing a Square Reference > Mathematics > Algebra > The Quadratic Formula With some quadratics, it's possible to look at them and -- at a glance, recognize that they are almost perfect …... Being able to solve quadratic equations is an essential skill necessary for a number of topics such as curve sketching, and for finding the minimum or maximum values to solve real-life problems.

**Quadratic Equations Perfect Maths**

If you need to complete the square in order to solve a quadratic equation, you must square a binomial and produce a perfect square trinomial. For example, if we have For example, if we have (x + 3) 2 , the perfect square trinomial would be: x 2 + 6x + 9 .... How to Find the Square Root of a Number We could say that the formula for creating a perfect square is . x * x. Where x is any integer. And if we want to determine a specific perfect square

**Solving quadratic by completing the square with an example.**

The quadratic formula Here is a formula for finding the roots of any quadratic. It is proved by completing the square In other words, the quadratic formula completes the square for us.... To make any equation a perfect square follow these steps.... First of all you must realise that the variable to consider here is 'n'. Then make the coefficient of n^2 to unity by dividing throughout the equation. Then add to the equation the square of half the coefficient of n. Simply it to get a perfect square. If you didn't understand it then tell me I'll explain with examples. :)

10/09/2016 · So if x=y, then the above quadratic expression has a perfect square. But since we are only taking x and m as integer, here too y has to be an integer. But since we are only taking x and m as integer, here too y has to be an integer.... The equation has (unequal) irrational (surd form) roots if and only if D ? b 2 – 4ac > 0 and not a perfect square even if a, b and c are rational. In this case if p + vq, p,q rational is an irrational root, then p – vq is also a root (a, b, c being rational).

## How To Find The Perfect Square Of A Quadratic Equation

### The other two methods, the quadratic formula and completing the square, will both work flawlessly every time, for every quadratic equation. Of those two, the quadratic formula is the easier, but you should still learn how to complete the square.

- An equation in which one side is a perfect square trinomial can be easily solved by taking the square root of each side. Easy is good, so we basically want to force the quadratic equation into the form (x+a)?=x?+2ax+a?.
- Completing the square comes in handy when you’re asked to solve an unfactorable quadratic equation and when you need to graph conic sections (circles, ellipses, parabolas, and hyperbolas). You should only find the roots of a quadratic using this technique when you’re specifically asked to do so
