question\nexpress as a trinomial.\n$(x - 2)(3x + 1)$

Explanation:

Step1: Use FOIL method

$(x - 2)(3x+1)=x\times(3x + 1)-2\times(3x + 1)$

Step2: Distribute $x$ and $- 2$

$x\times(3x + 1)-2\times(3x + 1)=3x^{2}+x-6x - 2$

Step3: Combine like - terms

$3x^{2}+x-6x - 2=3x^{2}-5x - 2$

Answer:

$3x^{2}-5x - 2$
