Answer:

x = 0, x = 4

Explanation:

Unfortunately, the equation 9x^2 - 36x = 0 cannot be solved using the square root method directly. The square root method is used to solve quadratic equations of the form ax^2 + bx + c = 0 by isolating the x^2 term, taking the square root of both sides, and solving for x. However, in the given equation, there is no constant term (c = 0), and therefore, we need to use a different method to solve it.

As I mentioned earlier, we can factor the equation and use the zero product property to solve for x. This method involves finding two factors of the quadratic equation that multiply to give 0, setting each factor equal to 0, and solving for x. In this case, we can factor out x and obtain the factors x and (9x - 36), which multiply to give 0. By setting each factor equal to 0 and solving for x, we obtain the solutions x = 0 and x = 4.

To solve the equation 9x^2 - 36x = 0 using the factorization method:

Factor out x from the left-hand side of the equation to get:

x(9x - 36) = 0

Apply the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. So, set each factor equal to zero and solve for x:

x = 0 or 9x - 36 = 0

For the second equation, solve for x:

9x - 36 = 0

9x = 36

x = 4

Therefore, the solutions to the equation are x = 0 and x = 4.

Note that this method involves factoring the quadratic equation and then using the zero product property to obtain the solutions. It works for any quadratic equation of the form ax^2 + bx + c = 0, where a, b, and c are constants, and a is not equal to zero.

Answer:

Explanation:

To solve the equation 9x^2 - 36x = 0 by using the square root method, we first need to rearrange the terms to get x^2 and x on one side:

9x^2 - 36x = 0

Factor out 9x from the left-hand side:

9x(x - 4) = 0

Now we have two factors: 9x = 0 and x - 4 = 0. Solving for x in each factor gives us:

9x = 0: x = 0

x - 4 = 0: x = 4

Therefore, the solutions to the equation are x = 0 and x = 4.
