What is the equation of the line of symmetry of the parabola y=3x^2-12x+15?

Thank you!

Thanks! Would you mind explaining it, if it's not any trouble? I'm having trouble understanding this ðŸ˜…

The x coordinate of the vertex of the standard parabola is the line of symmetry for a parabola

to find the x value of the vertex x = - b/2a (derived from finding the midpoint between the zeroes from using the quadratic equation)
