5x + 5y = 5(x+y)
5+5x5=30 but (5+5)x5=50
1,565 = x5 1,5651/5 = (x5)1/5 1,5651/5 = x5/5 1,5651/5 = x 4.3541 = x
5
The x^5 at the beginning makes the degree of the polynomial 5.
-5

x^5+2x^4+4x^2+2x-3
is a quintic expression in x (NOT an equation).
x^5+x^4+7x^2+x-2
(x5+ 5) / (x+5) = x^4 - 5x^3 + 25 x^2 - 125 x + 625 + (-3025 +5)/(x+5) = x^4 - 5x^3 + 25 x^2 - 125 x + 625 - 3020/(x+5) If I understand the problem correctly, that can't be simplified. You can only get an actual value if you substitute a value for "x".
