factor z^3-7z^2-9z+63

factor

z^{3} - 7 z^{2} - 9 z + 63

(z - 7) (z + 3) (z - 3)

Solution steps

z^{3} - 7 z^{2} - 9 z + 63

= (z^{3} - 7 z^{2}) + (- 9 z + 63)

Factor out

z^{2}

from

z^{3} - 7 z^{2} : z^{2} (z - 7)

Factor out

- 9

from

- 9 z + 63 : - 9 (z - 7)

= z^{2} (z - 7) - 9 (z - 7)

Factor out common term

z - 7

= (z - 7) (z^{2} - 9)

Factor

z^{2} - 9 : (z + 3) (z - 3)

= (z - 7) (z + 3) (z - 3)

1 0^{l o g_{10} (x)}

\frac{8}{3} - \frac{2}{8}

\frac{4 ^{2}}{4 ^{3}}

\frac{9 !}{8 !}

(- \frac{4}{9}) - (- \frac{5}{18})
