what is the difference of the two polynomials?\n$(7y^{2}+6xy)-(-2xy + 3)$\n$7y^{2}+4xy - 3$\n$7y^{2}+8xy - 3$\n$7y^{2}+4xy + 3$\n$7y^{2}+8xy + 3$
Answer
Explanation:
Step1: Remove parentheses
$$(7y^{2}+6xy)-(-2xy + 3)=7y^{2}+6xy + 2xy-3$$
Step2: Combine like - terms
$$7y^{2}+(6xy + 2xy)-3=7y^{2}+8xy-3$$
Answer:
(7y^{2}+8xy - 3) (the second option)
