Question

PLZ HELP I will give the brain 100 points!! Which of the following statements is true about completing the​ square? 1. When completing the square, add the square of half the coefficient of x to only the x^2+bx side of the equation. 2. When completing the square, add the square of half the coefficient of x to both sides of the equation. 3. When completing the square, subtract the square of half the coefficient of x from both sides of the equation. 4. When completing the square, add half the coefficient of x to both sides of the equation.

Answer 1

`\huge \boxed{\mathrm{Option \ 2 }}`

`\rule[225]{225}{2}`

Explanation:

When completing the square, we add the square of half the coefficient of x to both sides of the equation.

`\Longrightarrow \ \displaystyle ( (b)/(2) ) ^2`

Where b is the coefficient of x in the equation.

`\rule[225]{225}{2}`

Answer 2

2. When completing the square, add the square of half the coefficient of x to both sides of the equation.

Explanation:

1. When completing the square, add the square of half the coefficient of x to only the x^2+bx side of the equation.

False, it is added to both sides

2. When completing the square, add the square of half the coefficient of x to both sides of the equation.

True

3. When completing the square, subtract the square of half the coefficient of x from both sides of the equation.

We add it to both sides

4. When completing the square, add half the coefficient of x to both sides of the equation.

False we add the square to both sides
