How do you solve for x in the equation 3x² = 18?

by

Solving the Equation: 3x² = 18

To solve the equation 3x² = 18, follow these steps:

  1. Isolate x²:

    First, we need to get x² by itself on one side of the equation. To do this, divide both sides by 3:

    x² = 18 / 3

    This simplifies to:

    x² = 6

  2. Take the Square Root:

    Next, we find the value of x by taking the square root of both sides. Remember that taking the square root gives us both a positive and a negative solution:

    x = ±√6

  3. Final Solutions:

    Thus, the solutions to the equation are:

    x = √6 and x = -√6

In conclusion, the values of x that satisfy the initial equation are √6 and -√6.
