Missing term = –2xy
Solution:
Let us first find the quotient of .
Taking common term xy outside in the numerator.
Both xy in the numerator and denominator are cancelled.
Thus, the quotient of is
.
Given the quotient of is same as the product of 4xy and ____.
× missing term
Divide both sides by 4xy, we get
⇒ missing term =
Cancel the common terms in both numerator and denominator.
⇒ missing term = –2xy
Hence the missing term of the product is –2xy.
