- In the problem, x^2+2x+1 can be written as (x+1)^2 which implies (x+1)^2 + y^2 =0
So, for sum of two squares to become 0, both must be 0, which implies:
(x+1)^2 = 0. So x=-1, and therefore x^31+x^35 = -1 + -1 = -2
So, the answer must be -2. - 12 years agoHelpfull: Yes(68) No(1)
- x^2 + y^2 + 2x + 1=(x+1)^2+y^2=0
So, x=-1
and x^31+x^35=-1-1=-2

- x^2+y^2+2x+1=0;
it is more easy to find the values of x and y by
(x+1)^2 +y^2=0; x=-1,y=0;
so putting these values in x^31+x^35 it will be
-1 + -1 = -2
so ans is -2
