Answer:

B. 9x^2 - 12x + 6; quadratic trinomial

Step-by-step explanation:

[tex]6-12x+13x^2-4x^2\qquad\text{combine like terms}\\\\=(13x^2-4x^2)-12x+6\\\\=9x^2-12x+6\to\text{quadratic trinominal}\\\\\text{quadratic because we have}\ x^2\\\\\text{trinominal because we have three terms}\ 9x^2,\ -12x\ \text{and}\ 6[/tex]
