Question

F.O.I.L

Answer 1

If you are talking about what is in between the two sets of parentheses then the answer would be multiplication hope that helped

Answer 2

The answer is x^2 -7x +12

so (x-4)(x-3) multiply each one 

x*x is x^2 x*-3 is -3x

-4*x is -4x and -4*-3 is 12

combine like terms is -4x+-3x is -12x

put it all together now. 

x^2 - 7x + 12
