-7$x^{2}$ - 4x + 4; Quadratic trinomial

Work Step by Step

STEP1: Write out the original expression 6$x^{2}$ - 13$x^{2}$ - 4x + 4 =-7$x^{2}$ - 4x + 4 The expression has 3 terms in it, thus classifying itself as a trinomial. STEP 2: Make sure that the trinomial is in standard form, meaning that its terms are arranged from greatest exponent value to least exponent value. STEP 3: Determine the degree of the trinomial. The degree is the greatest exponent value, and in -7$x^{2}$ - 4x + 4, the degree is 2. The name of a trinomial with a degree of 2 is a quadratic trinomial.
