Answer: Last

Explanation:

FOIL stands for:

  • first
  • outside
  • inside
  • last

Multiply the first terms:


\sf{3x*2x=6x^2}

Multiply the outside terms:


\sf{3x*(-1)=-3x}

Multiply the inside terms:


\sf{5*2x=10x}

Multiply the last terms:


\sf{5*(-1)=-5}

The expression is:


\sf{6x^2-5x+10x-5}


\sf{6x^2+5x-5}
