For the expression 5x? y3 + xy2 + 8 to be a trinomial with a degree of 5, the missing exponent on the x-term must be .

2

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of the variable within the expression

y³ is of degree 3

xy² is of degree 1 + 2 = 3 ← sum the exponents of the 2 variables

Thus x²y³ is of degree 2 + 3 = 5

For the expression 5x?y³ + xy² + 8 to be a trinomial with a degree of 5, then the missing exponent of the x term must be 2.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomials are classified based on degree as linear, quadratic, cubic and so on. A trinomial is a polynomial with three terms.

For the expression 5x?y³ + xy² + 8 to be a trinomial with a degree of 5, then the missing exponent of the x term must be 2.
