expand (z-1.2)(z-0.5)(z+0.4)

expand

(z - 1.2) (z - 0.5) (z + 0.4)

z^{3} - 1.3 z^{2} - 0.08 z + 0.24

Solution steps

(z - 1.2) (z - 0.5) (z + 0.4)

Expand

(z - 1.2) (z - 0.5) : z^{2} - 1.7 z + 0.6

= (z^{2} - 1.7 z + 0.6) (z + 0.4)

Expand

(z^{2} - 1.7 z + 0.6) (z + 0.4) : z^{3} - 1.3 z^{2} - 0.08 z + 0.24

= z^{3} - 1.3 z^{2} - 0.08 z + 0.24

\frac{( 2 + x ^{2} ) ^{3}}{6}

x - 1 \cdot (x - 2)

(x^{(8)} - 4 x^{(3)} - x) d x

(sec (x) - 1) (sec (x))

\frac{( 2 y + 8 ) ^{2}}{4}
