Solve the following quadratic equation using square

Question

roots: (𝑥 + 12) over
= 9

Answer 1

To solve the quadratic equation \(\frac{x + 12}{1} = 9\), we can first simplify it:

1. Start with the equation: \[ \frac{x + 12}{1} = 9 \]

2. Multiply both sides by 1 (which doesn't change the equation): \[ x + 12 = 9 \]

3. Now, isolate \(x\) by subtracting 12 from both sides: \[ x = 9 - 12 \] \[ x = -3 \]

So the solution to the equation is: \[ \boxed{-3} \]
