y + 1

10

$y^{2}$ + 4 xy + 1

Solution

Equation Variable Constant

2 $x^{3}$ + 3 $y^{2}$ x , y No constanats

y + 1 y 1

10 No variables 10

$y^{2}$ + 4xy + 1 x , y 1

For $2 x^{3} + 3 y^{2}$ , we have the terms $2 x^{3} + 3 y^{2}$ . The variables are x and y , and there are no constant terms.

For $y + 1, y$ is the variable part and 1 is the constant.

For 10 , there is no variable part and 10 is the constant.
For $y^{2} + 4 x y + 1$ , $x$ and $y$ are variables and 1 is constant.
