Please help! :(( The one I need help in is "What is the equation after you factor the binomial?"

Answer:
see below
Step-by-step explanation:
this is difference of the squares a² -b² =(a-b)(a +b)
a² =1/9 x² → a = √1/9x² =1/3 x
b² =25 → b = √25 = 5
finally 0 = -1 (1/3x -5)(1/3x5) or
[tex]0 = -1 (\frac{x}{3} -5)(\frac{x}{3} +5)[/tex]
