The line of symmetry of the parabola whose equation is y = ax^2 - 4x + 3 is x = -(-4)/2a = -2. Solve the equation we get a = -1

What is the solution set of the following equation? 3x^2 - 6x = 0
Question
Updated 11/18/2014 9:06:42 PM
3x^2 - 6x = 0
3x(x - 2) = 0
x = 0 or x = 2
The solution set for the equation 3x^2 - 6x = 0 is {0, 2}
