what is the difference of the two polynomials? (7y² + 6xy) - (-2xy + 3) o 7y² + 4xy - 3 o 7y² + 8xy - 3 o 7y² + 4xy + 3 o 7y² + 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:
$7y^{2}+8xy - 3$ (corresponding to the second option)
