"how to solve this equation 5z2 - 15z = 0"

5z^2 - 15z = 0
5z(z - 3) = 0 {factored out the greatest common factor, 5z}
5z = 0 or z - 3 = 0 {set each factor equal to 0}
z = 0 or z = 3 {solved each equation for z}

5z%5E2-15z=0


5z%28z-3%29=0


5z=0 or z-3=0


z=0 or z=3


So the solutions are z=0 or z=3
