Question

What is the difference of the polynomials? (m^2n^2-7)-(mn+4)

Answer 1

Answer: The difference is,

$m^2n^2-mn-11$

Step-by-step explanation:

Given expression is,

$(m^2n^2-7)-(mn+4)$

By distributive property,

$m^2n^2-7-mn-4$

Combine like terms( that have the same variables and powers ),

$m^2n^2-mn-11$

Which is the required result.

Hence, option third is correct.
