Answer:
(x+y)(x-y-1)
Step-by-step explanation:
x²-y²-x-y= (x+y)(x-y)-(x+y)= (x+y)(x-y-1)
Answer:
-4x^3 + 7y^3 + 5
Step-by-step explanation:
7y^3 - 7x^3 + 4 - 5 + 6 - 3x^3 + 6x^3 Given
7y^3 - 7x^3 - 3x^3 + 6x^3 + 4 - 5 + 6 Rearrange
7y^3 - 4x^3 + 5 Combine the like terms
or
-4x^3 + 7y^3 + 5 Answer
The answer to question seven and question nine is
Answer:
