Answer:
The coefficients in the expression are: 12, 2,4 and 7
Step-by-step explanation:
Expressions like this are known as polynomials in two variables.
In a general form a polynomial in two variables is an expression that can be written in the form:
, where or are called the coefficients.
To get polynomial coefficients, you can take the numbers in front of each terms, for example is known as term and the coefficient is 12.
Or compare the general form of a polynomial with the polynomial and you find that the coefficients in the expression are: 12, 2,4 and 7
