expand 0.8(z-0.6)(z-0.8)

expand

0.8 (z - 0.6) (z - 0.8)

0.8 z^{2} - 1.12 z + 0.384

Solution steps

0.8 (z - 0.6) (z - 0.8)

Expand

0.8 (z - 0.6) (z - 0.8) : 0.8 (z^{2} - 1.4 z + 0.48)

= 0.8 (z^{2} - 1.4 z + 0.48)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

0.8 (z^{2} - 1.4 z + 0.48) = 0.8 z^{2} + 0.8 (- 1.4 z) + 0.8 \cdot 0.48

= 0.8 z^{2} + 0.8 (- 1.4 z) + 0.8 \cdot 0.48

Simplify

0.8 z^{2} + 0.8 (- 1.4 z) + 0.8 \cdot 0.48 : 0.8 z^{2} - 1.12 z + 0.384

= 0.8 z^{2} - 1.12 z + 0.384

(3 - y)^{6}

a \cdot b + (a - 1) \cdot b^{2} + (a - 2) \cdot b^{3}

3 m^{3} b^{2} - 9 b^{3} m^{4}

84 x^{3} + 404 x^{2} + 597 x + 280
