Answer:

-x^2-2x-3

Step-by-step explanation:

  • Question 1: Just substitute in the values of f(x) and g(x) and simplify!

  1. f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
  2. f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
  3. f(x)-g(x) = -x^2-2x-3

Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)

Hope this helps!!
