Question

solve (xy-3)^2 using FOIL

Answer 1

(xy-3)(xy-3)
xy^2 - 3xy -3xy +9
xy^2 - 6xy +9

basically you take the first xy multiply it by both parts in the second parenthesis and then do the same with the 3

Answer 2

(xy - 3)(xy - 3)

Foil: First Inside, Ouside Last
inside -------- outside
xy*xy -3xy -3xy + 9

(x^2)(y^2) - 6xy + 9

Answer 3

x^2y^2-(2)(3xy)+9

Answer 4

(xy-3)(xy-3) = x^2y^2 - 3xy -3xy +9
= x^2y^2 -6xy + 9

Answer 5
