Let number be x
From question
x+x²=182
x+x²-182=0
x²+x-182=0
x²+14x-13x-182=0
x(x+14)-13(x+14)=0
(x+14)(x-13)=0
So x is either -14 or 13.
-14 is not possible due to the given criterion of the question
So the number is 13.
Can we put (2x +1)+(2x+1)^2=182
Because 2x+1is a odd no.
Because 2x+1is a odd no.
No
Solving it you’ll get different answers
And 2x+1 is not odd
because x can be a decimal like 0.5
