#### Answer

$x^{2}$ - 3x + 4; Quadratic trinomial

#### Work Step by Step

STEP 1: Write out the original expression. $x^{2}$ + 4 - 3x The expression has 3 terms in it, thus classifying itself as a trinomial STEP 2: Arrange the trinomial into standard form, meaning that the terms are listed from greatest exponent value to the least exponent value. $x^{2}$ - 3x + 4 The degree is the greatest exponent value, and in $x^{2}$ - 3x + 4, the degree is 2. The name of a trinomial with a degree of 2 is a quadratic trinomial.
