Question

How do you solve `2x = x^2`?

Answer 1

x= 0 , x = 2

Explanation:

Since there is a 'squared' term in this equation that means it is a quadratic equation.

collect terms to 1 side and equate to zero.

hence `x^2 - 2x = 0`

there is a common factor of x → x(x-2) = 0

then x = 0 or x-2 = 0 → x = 2
