factor x^{900}-1

Solution

factor

x^{900} - 1

Solution

(x^{2} + 1) (x^{48} - x^{46} + x^{44} - x^{42} + x^{40} - x^{38} + x^{36} - x^{34} + x^{32} - x^{30} + x^{28} - x^{26} + x^{24} - x^{22} + x^{20} - x^{18} + x^{16} - x^{14} + x^{12} - x^{10} + x^{8} - x^{6} + x^{4} - x^{2} + 1) (x + 1) (x^{24} - x^{23} + x^{22} - x^{21} + x^{20} - x^{19} + x^{18} - x^{17} + x^{16} - x^{15} + x^{14} - x^{13} + x^{12} - x^{11} + x^{10} - x^{9} + x^{8} - x^{7} + x^{6} - x^{5} + x^{4} - x^{3} + x^{2} - x + 1) (x - 1) (x^{24} + x^{23} + x^{22} + x^{21} + x^{20} + x^{19} + x^{18} + x^{17} + x^{16} + x^{15} + x^{14} + x^{13} + x^{12} + x^{11} + x^{10} + x^{9} + x^{8} + x^{7} + x^{6} + x^{5} + x^{4} + x^{3} + x^{2} + x + 1) (x^{200} + x^{100} + 1) (x^{600} + x^{300} + 1)

Solution steps

x^{900} - 1

Rewrite

x^{900} - 1

as

(x^{300})^{3} - 1^{3}

= (x^{300})^{3} - 1^{3}

Apply Difference of Cubes Formula:

x^{3} - y^{3} = (x - y) (x^{2} + x y + y^{2})

(x^{300})^{3} - 1^{3} = (x^{300} - 1) (x^{600} + x^{300} + 1)

= (x^{300} - 1) (x^{600} + x^{300} + 1)

Factor
