Rural living has its benefits and drawbacks. One of the biggest pluses is the low cost of living, which allows people to save more. The fresh air and green spaces are great for health and well-being. Furthermore, the people here are generally very hospitable and friendly, creating a warm community.

P(x)+Q(x)=(x⁴-5x³+4x-5)+(-4+3x²+2x+1)
=x⁴-5x³+4x-5-4+3x+2x+1
=x⁴-5x³+(4x+3x+2x)+(-5-4+1)
=x⁴-5x³+9x+(-8)
=x⁴-5x³+9x-8
