If m = baseball cards he had yesterday, and today he got rid of 5, the expression is equal to

m - 5 = x.

As an example of what the answer is, replace m with 10.

If he had 10 baseball cards and gave away 5 today, x = 5.

The answer is m - 5 = x.

The quotient of 5n^2(m^2+2m-3)/10n(m^2-3m+2) divided by n^2(m^2-3m-18)/4n^2(m^2-8m+12)
slavikrds [6]
\dfrac{ 5n^2(m^2+2m-3)}{10n(m^2-3m+2)} \div  \dfrac{n^2(m^2-3m-18)}{4n^2(m^2-8m+12)}

\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \div  \dfrac{n^2(m + 3)(m - 6)}{4n^2(m - 2)(m - 6)}

\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \times  \dfrac{4n^2(m - 2)(m - 6)}{n^2(m + 3)(m - 6)}

= 2n
