factor z^3-0.2z^2-z+0.2

factor

z^{3} - 0.2 z^{2} - z + 0.2

(1 + z) (- 1 + z) (z - 0.2)

Solution steps

z^{3} - 0.2 z^{2} - z + 0.2

Factor

z^{3} - z : z (z + 1) (z - 1)

Factor

- 0.2 z^{2} + 0.2 : - 0.2 (z + 1) (z - 1)

= z (z + 1) (z - 1) - 0.2 (z + 1) (z - 1)

Factor out common term

(1 + z) (- 1 + z)

= (1 + z) (- 1 + z) (z - 0.2)

(- cos (x)) ln (sec (x) + tan (x))

x^{3 - 7 x - 6}

(x - 2)^{2} - (2 - x) (x + 4) i ze

30 x^{3} + 1 5^{2} - 18 x - 9

- \frac{4}{9} x + 4
