Solution:
The equation given in the image is:x^2 - 7 = 0To solve for x, follow these steps:1. Add 7 to both sides of the equation to isolate the x^2 term:x^2 - 7 + 7 = 0 + 7x^2 = 72. Take the square root of both sides to solve for x:√(x^2) = ±√7x = ±√7Therefore, the solutions for x are x = √7 and x = -√7.
