expand (m-4)(m^2+4m-5)

expand

(m - 4) (m^{2} + 4 m - 5)

m^{3} - 21 m + 20

Solution steps

(m - 4) (m^{2} + 4 m - 5)

Distribute parentheses

= m m^{2} + m \cdot 4 m + m (- 5) - 4 m^{2} - 4 \cdot 4 m - 4 (- 5)

Simplify

m m^{2} + m \cdot 4 m + m (- 5) - 4 m^{2} - 4 \cdot 4 m - 4 (- 5) : m^{3} - 21 m + 20

= m^{3} - 21 m + 20

\frac{5 3}{5}

x^{8} \cdot x^{5}

\frac{1}{sinh ( x )}

\frac{40}{927} - (- \frac{2}{3}) + 1

e^{0.7005}
