Subtract the Polynomials (4x4+5xyy3)(x4+3xy+5y3)\left( 4 x ^ { 4 } + 5 x y - y ^ { 3 } \right) - \left( x ^ { 4 } + 3 x y + 5 y ^ { 3 } \right)

Question 68

Multiple Choice

Subtract the polynomials. Assume all variable exponents represent whole numbers.
- (4x4+5xyy3) (x4+3xy+5y3) \left( 4 x ^ { 4 } + 5 x y - y ^ { 3 } \right) - \left( x ^ { 4 } + 3 x y + 5 y ^ { 3 } \right)


A) 4x4+2xy6y34 x ^ { 4 } + 2 x y - 6 y ^ { 3 }
B) 3x4+2xy6y33 x ^ { 4 } + 2 x y - 6 y ^ { 3 }
C) 3x4+2xy4y33 x ^ { 4 } + 2 x y - 4 y ^ { 3 }
D) 5x4+12xy+4y35 x ^ { 4 } + 12 x y + 4 y ^ { 3 }
