Answer 2

Let that number be x.

x is added to its square

square of x is x²

Adding x² with x gives 6

==> x+x²=6

==>x(x+1)=6

Now think that if x is 2 then x+1 is 3

x(x+1) = 2*3 =6

and also

when x is -3

(-3)(-3+1)

=(-3)(-2) =6

So 2 and -3 satisfies the value of x

The number is either 2 or -3

Hope it helps
