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.

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

Step-by-step 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

Step-by-step explanation:

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

Where b is the coefficient of x in the equation.

5x+2x=49

7x=49

x=7. 35 apples

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
