Here are the essential concepts you must grasp in order to answer the question correctly.
Quadratic Equations
A quadratic equation is a polynomial equation of the form ax^2 + bx + c = 0, where a, b, and c are constants and a ≠ 0. The solutions to these equations can be found using various methods, including factoring, completing the square, or applying the quadratic formula. In the case of x^2 = 25, it can be rearranged to the standard form and solved accordingly.

Square Roots
Square roots are the values that, when multiplied by themselves, yield the original number. For example, the square root of 25 is 5, since 5 * 5 = 25. When solving equations like x^2 = 25, taking the square root of both sides leads to two potential solutions: x = 5 and x = -5, reflecting the property that both positive and negative values can satisfy the equation.

Solution Sets
A solution set is the collection of all possible solutions to an equation. For quadratic equations, the solution set can include one solution (a repeated root), two distinct solutions, or no real solutions at all. In the case of x^2 = 25, the solution set is {5, -5}, indicating that both values satisfy the original equation.
