Full solution

Q. h2−4h=0h^2 - 4h = 0
  1. Factor out hh: Factor out hh from the left side of the equation: h(h−4)=0h(h - 4) = 0.
  2. Set equal and solve: Set each factor equal to zero and solve for hh: h=0h = 0 and h−4=0h - 4 = 0.
  3. Solve for h=4h = 4: Solve the second equation: h−4=0h - 4 = 0, so h=4h = 4.
