Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.
w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.
Idk :) but the other guy answering might be able to help you. please give me a like!
Are you missing an option? The answer should be -2/3 (I just calculated it numerous times)
