Find the missing term.

Mathematics

5 0

Equations are used to relate equal expressions.

The missing term is: \mathbf{  m -1}

The equation is given as:

\mathbf{\frac{m - n}{m^2 - n^2} + \frac{?}{(m -1)(m -n)} = \frac{2m}{m^2 - n^2}}

Express \mathbf{m^2 - n^2\ as\ (m - n)(m + n)}

So, we have:

\mathbf{\frac{m - n}{(m - n)(m + n)} + \frac{?}{(m -1)(m -n)} = \frac{2m}{(m - n)(m + n)}}

Multiply through by \mathbf{m - n}

\mathbf{\frac{m - n}{m + n} + \frac{?}{m -1} = \frac{2m}{m + n}}

Collect like terms

\mathbf{ \frac{?}{m -1} = \frac{2m}{m + n} - \frac{m - n}{m + n}}

Take LCM

\mathbf{ \frac{?}{m -1} = \frac{2m - m + n}{m + n} }

\mathbf{ \frac{?}{m -1} = \frac{m + n}{m + n} }

Divide \mathbf{ \frac{m + n}{m + n} }

\mathbf{ \frac{?}{m -1} = 1}

Cross multiply

\mathbf{ ? =(m -1)\times 1}

\mathbf{ ? =m -1}

Hence, the missing term is: \mathbf{  m -1}
