Answer:

C) Chase did not make a mistake.

Step-by-step explanation:

\tt \cfrac{1}{3} \:(g-3)=3

\tt g-3=9  ( step#1 )

\tt g=12  ( step#2 )

Step 1: Divided each side of the equation by 1/3 which is correct.

Step 2: simplified from g - 3 = 9 to g=12

Therefore, Chase didn't make a mistake.

After completing the square, what are the solutions to the quadratic equation
Fiesta28 [93]

Answer:

x_1= \frac{\sqrt{{29}}}{2} +\frac{7}{2}\\\\x_2= -\frac{\sqrt{{29}}}{2} +\frac{7}{2}

Step-by-step explanation:

1. Subtract 9 from both sides of the equation:

x^2 - 7x+9-9 = 4-9\\\\x^2 - 7x= -5

2. Notice that the coefficient of "x" is 7. Then:

(\frac{7}{2})^2=\frac{49}{4}

3. Add \frac{49}{4} to both sides of the equation:

x^2 - 7x+\frac{49}{4}= \frac{49}{4}-5\\\\x^2 - 7x+\frac{49}{4}= \frac{29}{4}

4. Completing the square, you get:

(x -\frac{7}{2})^2= \frac{29}{4}

5. To find the solutions, you must  square-root both sides of the equation, simplify, and solve for "x". Then, you get:

\sqrt{(x -\frac{7}{2})^2}= \±\sqrt{\frac{29}{4}}\\\\x -\frac{7}{2}=\±\frac{\sqrt{{29}}}{2} \\\\x= \±\frac{\sqrt{{29}}}{2} +\frac{7}{2}\\\\\\x_1= \frac{\sqrt{{29}}}{2} +\frac{7}{2}\\\\x_2= -\frac{\sqrt{{29}}}{2} +\frac{7}{2}
