Question 170

Multiple Choice

Factor the trinomial completely. If the polynomial cannot be factored, write "prime."
- x3y+7x2y218xy3x ^ { 3 } y + 7 x ^ { 2 } y ^ { 2 } - 18 x y ^ { 3 }


A) xy(x2+7x18y2) x y \left( x ^ { 2 } + 7 x - 18 y ^ { 2 } \right)
B) x(xy2y2) (x+9y) x \left( x y - 2 y ^ { 2 } \right) ( x + 9 y )
C) xy(x2y) (x+9y) x y ( x - 2 y ) ( x + 9 y )
D) y(x2y) (xy+9y2) y ( x - 2 y ) \left( x y + 9 y ^ { 2 } \right)
