What is the equation of the line of symmetry of the parabola y=3x^2-12x+15?
it will be x = - b/2a
Thanks! Would you mind explaining it, if it's not any trouble? I'm having trouble understanding this 😅
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)
