A.) 7y^2 + 4xy – 3
B.) 7y^2 + 8xy – 3
C.) 7y^2 + 4xy + 3
D.) 7y^2 + 8xy + 3
Answer:
B) 7y² + 8xy - 3 .
Step-by-step explanation:
Given : (7y² + 6xy) – (–2xy + 3).
To find : What is the difference of the two polynomials.
Solution : We have given
(7y² + 6xy) – (–2xy + 3).
Removing the pantheists
(7y² + 6xy) + 2xy - 3).
Combine like terms
7y² + 8xy - 3 .
Therefore, B) 7y² + 8xy - 3 .
