## How do you explain completing the square?

Completing the square means writing a quadratic in the form of a squared bracket and adding a constant if necessary. One application of completing the square is finding the maximum or minimum value of the function, and when it occurs.

### Why does complete the square work?

When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. That’s just a fancy way of saying that completing the square is a technique that transforms your quadratic equation from an equation that can’t be factored into one that can.

#### Why is it called completing the square?

Talk the Talk This procedure is called completing the square because, by adding 16 to both sides in Example 2, you’re creating a trinomial that’s a perfect square. Therefore, it can be written as (x + a)2, where a is the number from the bug’s midsection.

**How do you complete the square in Class 10?**

Step 1: Write the equation in the form, such that c is on the right side. Step 2: If a is not equal to 1, divide the complete equation by a such that the coefficient of x2 will be 1. Step 3: Now add the square of half of the coefficient of term-x, (b/2a)2, on both sides.

**Why does completing the square give the turning point?**

Why is it when you turn a quadratic into the form of completing the square, why does this give the turning point? It’s all to do with translations. If you’ve got some function, f(x), you can translate it (i.e. move it) a units to the right by subtracting a from every x value, f(x – a).

## When should you complete the square?

Next, if the coefficient of the squared term is 1 and the coefficient of the linear (middle) term is even, completing the square is a good method to use.

### Who first completed the square?

Al-Khwarizmi, as Muhammed is more commonly called, solved quadratic equations by the method we call today, completing the square.

#### How do you complete the square calculator?
