Q
Q: If 4x^2 - 16 = 0, what is the value of x?
Solution:
Add 16 to both sides: 4x^2 = 16. Divide by 4: x^2 = 4. Thus, x = ±2.
Steps: 4
Show Steps
Step 1: Start with the equation 4x^2 - 16 = 0.
Step 2: Add 16 to both sides of the equation to isolate the term with x. This gives you 4x^2 = 16.
Step 3: Now, divide both sides of the equation by 4 to simplify. This results in x^2 = 4.
Step 4: To find the value of x, take the square root of both sides. This gives you x = ±2.
