-- The highest power of 'x'in the expression is x², so it's a second-degree expression.

-- The expression has 3 terms ...  5x,  2x²,  and  -8  ... so it's a TRInomial.

Answer:

(C)second degree trinomial

Step-by-step explanation:

The given expression is:

[tex]5x+2x^2-8[/tex]

Now, Degree of the expression is defined as the highest power of the variable given in the expression, thus in the given expression that is [tex]5x+2x^2-8[/tex], the variable is x and the highest power of x is 2, therefore it is a second degree expression.

Also, Trinomial is an expression which consists of three terms, and also the given expression [tex]5x+2x^2-8[/tex] consists of three terms that are [tex]5x, 2x^2 and -8[/tex], therefore, the given expression is a second degree trinomial.
