Answer:
Let the first positive odd integer be x
another odd integer be (x+2)
square:
x^2(x+2)^2=290
x^2×x^2+4+4x=290
2x^2+4x+4=290
2x^2+4x=286=0
2x^2+4x-286=0
divide by 2
x^2+2x-143=0
x^2+13x-11x-143=0
x(x+13)-11(x+13)
(x-11)=0 (x+13)=0
x=11. x=-13
Positive number should be taken
So, the positive odd integer
Another positive odd integer (x+2)=11+2 =13
