m = 1, n = 2
Substitute in all expressions.
a) (2×1+2)(1-2)=-4
b) [tex](1+2^2)+(1-2^2)=5+(-3)=2[/tex]
c) [tex]1^2+1\times2+2^2=7[/tex]
d) 1+2=3

What is an odd number?
A number that cannot be split by two to produce two equal numbers will be an odd number.
Given;
If m is an odd integer and n an even integer,
Assume,
m=1
n=2
Put the values one by one in the options;
a)
[tex]\frac{(2m+n)}{(m-n)} \\\\ \frac{(2\times 1+2)}{(1-2)} \\\\ -4[/tex]
b)
[tex]{ (m+n^2)+(m-n^2)[/tex]
[tex]{ (1+2^2)+(1-2^2)[/tex]
[tex]2[/tex]
c)
[tex]\rm m^2+mn+n^2 \\\\ \rm 1^2+1 \times 2+2^2 \\\\ 7[/tex]
d)
[tex]m+n \\\\ 1+2 \\\\ 3[/tex]
Hence, the equations C and D will give the odd number after the solution.
