Q
Q: Solve for x: 3x^2 - 12 = 0.
Solution:
Add 12 to both sides: 3x^2 = 12. Divide by 3: x^2 = 4. Thus, x = ±2.
Steps: 4
Show Steps
Step 1: Start with the equation 3x^2 - 12 = 0.
Step 2: Add 12 to both sides of the equation to get 3x^2 = 12.
Step 3: Divide both sides by 3 to simplify the equation to x^2 = 4.
Step 4: Take the square root of both sides to find x. This gives you x = ±2.
