expand (x^2+5x+2)^7

Solution

expand

(x^{2} + 5 x + 2)^{7}

Solution

x^{14} + 35 x^{13} + 539 x^{12} + 4795 x^{11} + 27209 x^{10} + 102725 x^{9} + 261905 x^{8} + 451225 x^{7} + 523810 x^{6} + 410900 x^{5} + 217672 x^{4} + 76720 x^{3} + 17248 x^{2} + 2240 x + 128

Solution steps

(x^{2} + 5 x + 2)^{7}

(x^{2} + 5 x + 2)^{7} = (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2)

= (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2) (x^{2} + 5 x + 2)
