expand (-z^2+2z-1)^8

Solution

expand

(- z^{2} + 2 z - 1)^{8}

Solution

z^{16} - 16 z^{15} + 120 z^{14} - 560 z^{13} + 1820 z^{12} - 4368 z^{11} + 8008 z^{10} - 11440 z^{9} + 12870 z^{8} - 11440 z^{7} + 8008 z^{6} - 4368 z^{5} + 1820 z^{4} - 560 z^{3} + 120 z^{2} - 16 z + 1

Solution steps

(- z^{2} + 2 z - 1)^{8}

(- z^{2} + 2 z - 1)^{8} = (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1)

= (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1) (- z^{2} + 2 z - 1)

Expand
