question\nexpress as a trinomial.\n$(x - 6)(3x - 9)$

Explanation:

Step1: Use FOIL method

$(x - 6)(3x - 9)=x\times3x+x\times(- 9)+(-6)\times3x+(-6)\times(-9)$

Step2: Simplify each term

$x\times3x = 3x^{2}$, $x\times(-9)=-9x$, $(-6)\times3x=-18x$, $(-6)\times(-9) = 54$

Step3: Combine like - terms

$3x^{2}-9x-18x + 54=3x^{2}+(-9x-18x)+54=3x^{2}-27x + 54$

Answer:

$3x^{2}-27x + 54$
