Transcript text: Solve the equation. Simplify solutions and list from least to greatest, separated by a comma.
\[
3 x^{2}+48=0
\]
Solution
Solution Steps
To solve the quadratic equation \(3x^2 + 48 = 0\), we first isolate the \(x^2\) term by subtracting 48 from both sides and then dividing by 3. Next, we take the square root of both sides to solve for \(x\). Since the equation involves a negative number under the square root, the solutions will be complex numbers. Finally, we simplify the solutions and list them from least to greatest.
Step 1: Isolate the Quadratic Term
Starting with the equation \(3x^2 + 48 = 0\), we isolate the \(x^2\) term by subtracting 48 from both sides:
\[
3x^2 = -48
\]
Step 2: Divide by the Coefficient
Next, we divide both sides by 3 to simplify:
\[
x^2 = -16
\]
Step 3: Take the Square Root
Taking the square root of both sides, we find:
\[
x = \pm \sqrt{-16} = \pm 4i
\]
This gives us the two complex solutions: \(x_1 = 4i\) and \(x_2 = -4i\).
Step 4: List the Solutions
We list the solutions from least to greatest:
\[
x_2 = -4i, \quad x_1 = 4i
\]
Final Answer
The solutions to the equation \(3x^2 + 48 = 0\) are:
\[
\boxed{-4i, 4i}
\]
