expand ((m-2k+5)(m-2k+4))/((k-3)(k-2))

expand

\frac{( m - 2 k + 5 ) ( m - 2 k + 4 )}{( k - 3 ) ( k - 2 )}

\frac{- 4 km + m ^{2} + 9 m + 4 k ^{2} - 18 k + 20}{k ^{2} - 5 k + 6}

Solution steps

\frac{( m - 2 k + 5 ) ( m - 2 k + 4 )}{( k - 3 ) ( k - 2 )}

Expand

(k - 3) (k - 2) : k^{2} - 5 k + 6

= \frac{( m + 5 - 2 k ) ( m + 4 - 2 k )}{k ^{2} - 5 k + 6}

Expand

(m - 2 k + 5) (m - 2 k + 4) : - 4 km + m^{2} + 9 m + 4 k^{2} - 18 k + 20

= \frac{- 4 km + m ^{2} + 9 m + 4 k ^{2} - 18 k + 20}{k ^{2} - 5 k + 6}

\frac{e ^{- s} + 4 s - 28}{s ( - 7 + s )}
