# How do you complete a square in algebra?

## How do you complete a square in algebra?

Steps

1. Step 1 Divide all terms by a (the coefficient of x2).
2. Step 2 Move the number term (c/a) to the right side of the equation.
3. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

## What is an example of coefficient in math?

What is a Coefficient in Math? A coefficient is a number or an alphabet that is multiplied by a variable of a single term or the terms of a polynomial. For example, in the term 7x, 7 is the coefficient. The coefficient of x in the term 3xy is 3y.

What are the steps to completing the square?

The completing the square method involves the following steps:

1. Step 1) Divide all terms by the coefficient of .
2. Step 2) Find.
3. Step 3) Find.
4. Step 4) Add to both sides of the equation.
5. Step 5) Complete the square on the left-hand-side of the equation.
6. Step 7) Take the square root of both sides and solve for the variable.

Does the coefficient have to be 1 to complete the square?

Even if \begin{align*}b\end{align*} is not divisible by \begin{align*}a\end{align*}, the coefficient of \begin{align*}x^2\end{align*} needs to be 1 in order to complete the square. Step 3: Now, complete the square. Determine what number would make a perfect square trinomial.

### What are coefficients in algebra?

Coefficient is a number that is being multiplied by the variable. 2x+6x+14. The 2x, 6x, and 14 are terms because they are being added together. 2 and x; 6 and x are factors because they are being multiplied together. 2 from 2x and 6 from 6x are the coefficients because they are being multiplied by the variable.

### What is a coefficient in an algebraic expression?

coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

• ## How to factor by completing the square?

– Determine the values of 𝑎 and 𝑏. – Calculate 2 𝑎 𝑏. – Add 2 𝑎 𝑏 and − 2 𝑎 𝑏 to the expression. – Factor 𝑎 + 2 𝑎 𝑏 + 𝑏   as ( 𝑎 + 𝑏) , or factor 𝑎 − 2 𝑎 𝑏 + 𝑏   as ( 𝑎

## How do you solve the equation by completing the square?

Transform the equation so that the constant term,c,is alone on the right side.

• If a,the leading coefficient (the coefficient of the x 2 term),is not equal to 1,divide both sides by a .
• Add the square of half the coefficient of the x -term,( b 2 a) 2 to both sides of the equation.
• Factor the left side as the square of a binomial.
• What are the steps to complete the square?

Step 1 Divide all terms by a (the coefficient of x 2).; Step 2 Move the number term (c/a) to the right side of the equation.; Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.; We now have something that looks like (x + p) 2 = q, which can be solved rather easily: Step 4 Take the square root on both sides of
