#y=0" or "y=-5/2#

Explanation:

#"distribute the right side"#

#rArr3y^2=y^2-5y#

#"subtract "y^2-5y" from both sides"#

#rArr3y^2-y^2+5y=0#

#rArr2y^2+5y=0#

#"take out a "color(blue)"common factor of y"#

#y(2y+5)=0#

#"equate each factor to zero and solve for y"#

#rArry=0" or "2y+5=0rArry=-5/2#
