expand 4(z-1)(z-e^α)

Solution

expand

4 (z - 1) (z - e^{α})

Solution

4 z^{2} - 4 e^{α} z - 4 z + 4 e^{α}

Solution steps

4 (z - 1) (z - e^{α})

Expand

(z - 1) (z - e^{α}) : z^{2} - e^{α} z - z + e^{α}

= 4 (z^{2} - e^{α} z - z + e^{α})

Expand

4 (z^{2} - e^{α} z - z + e^{α}) : 4 z^{2} - 4 e^{α} z - 4 z + 4 e^{α}

= 4 z^{2} - 4 e^{α} z - 4 z + 4 e^{α}
