What are the solutions to the equation?

Short Answer

The equation (x − 25)² = 36 can be solved by taking the square root of both sides, resulting in two cases: x − 25 = 6 and x − 25 = -6. After isolating x, the solutions are found to be 19 and 31.

Step-by-Step Solution

Step 1: Understand the Equation

The equation we are dealing with is (x − 25)² = 36. This is a quadratic equation where we want to find the value of x. The goal is to isolate x by manipulating the equation using algebraic rules.

Step 2: Solve for x

To solve the equation, we first take the square root of both sides. This gives us two possibilities to consider:

  • x ‚àí 25 = 6
  • x ‚àí 25 = -6

Next, we will add 25 to both sides of each case, leading to two separate equations.

Step 3: Find the Solutions

After adding 25, we need to solve each case individually. This results in:

  • x = 25 + 6 ‚Üí x = 31
  • x = 25 – 6 ‚Üí x = 19

Thus, the solutions to the equation are 19 and 31.
