The equation x2 = 2x can be solved by first rearranging it into a standard quadratic form.
To do this, we can subtract 2x from both sides:
x2 - 2x = 0
Next, we can factor the left-hand side:
x(x - 2) = 0
This product is equal to zero when either factor is equal to zero. Therefore, we can set each factor to zero:
- x = 0
- x – 2 = 0 → x = 2
Thus, the solutions to the equation x2 = 2x are:
- x = 0
- x = 2
In conclusion, the solution set of the equation x2 = 2x is {0, 2}.
