expand (a^2+a-1)^5

expand

(a^{2} + a - 1)^{5}

a^{10} + 5 a^{9} + 5 a^{8} - 10 a^{7} - 15 a^{6} + 11 a^{5} + 15 a^{4} - 10 a^{3} - 5 a^{2} + 5 a - 1

Solution steps

(a^{2} + a - 1)^{5}

(a^{2} + a - 1)^{5} = (a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1)

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

Expand

(a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1) (a^{2} + a - 1) : a^{10} + 5 a^{9} + 5 a^{8} - 10 a^{7} - 15 a^{6} + 11 a^{5} + 15 a^{4} - 10 a^{3} - 5 a^{2} + 5 a - 1

= a^{10} + 5 a^{9} + 5 a^{8} - 10 a^{7} - 15 a^{6} + 11 a^{5} + 15 a^{4} - 10 a^{3} - 5 a^{2} + 5 a - 1
