Question

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

Answer 1

see below

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

`0 = -1 ((x)/(3) -5)((x)/(3) +5)`
