(a) 3z
(b) -2
(c) 7yz
(d) 7z
Solution:
Given, the expression is 3x²zy + 7xyz - 2z²x.
We have to find the coefficient of xy in the given expression.
Coefficient is the numerical factor in a term.
Sometimes, any factor in a term is called the coefficient of the remaining part of the term.
From the expression,
We observe that 7xyz = 7z(xy)
Therefore, the coefficient of xy is 7z.
