Perform Operations with Polynomials in Several Variables
-$$( x + 3 y ) ( 8 x - 11 y )$$
A) $8 x ^ { 2 } + 13 x y - 33 y ^ { 2 }$
B) $x ^ { 2 } + 13 x y - 33 y ^ { 2 }$
C) $8 x ^ { 2 } + 13 x y + 13 y ^ { 2 }$
D) $x ^ { 2 } + 13 x y + 13 y ^ { 2 }$

To solve this, use the distributive property (FOIL method for binomials): $(x + 3y)(8x - 11y) = 8x^2 - 11xy + 24xy - 33y^2 = 8x^2 + 13xy - 33y^2$.
