Thank you for the opportunity to help you with your question! I will do this step by step.

p = 25 - 0.01 s^2 (Original equation)

0 = 25 - 0.01 s^2 (set p = 0)

0 = (5 - 0.1s)(5 + 0.1s) (Factor, middle term cancels out)

Set each factor to 0

[0 = 5 - 0.1s] or [0 = 5 + 0.1s]

[-5 = -0.1s] or [-5 = 0.1s] (subtract 5 from both sides of both equations)

s = 50 or s = -50 (divide -5/-0.1 for first equation and -5/0.1 for second equation to solve)
