Question

Expand and simplify (x-3) (x-4)

Answer 1

Do FOIL (First, outer, inner, last)

(x-3)(x-4)
multiply the x's since they are first
then multiply -4 and x
then multiply -3 and x
then multiply -3 and -4
putting it all together gives you x^2-4x-3x+12
simplify and it will be x^2-7x+12

Answer 2

(x^2 - 7x + 12) That's my answer.
