X^2-4x=0

To solve the equation x^2 - 4x = 0, we can use the zero-product property. This property states that if the product of two factors is zero, then at least one of the factors must be zero.

Step 1: Factor the equation
x^2 - 4x = 0
x(x - 4) = 0

Step 2: Set each factor equal to zero and solve for x
x = 0 (from x = 0)
x - 4 = 0 (from x - 4 = 0)
x = 4

Therefore, the solution to the equation x^2 - 4x = 0 is x = 0 or x = 4.
