factor x^4-y^4+x^2-y^2

factor

x^{4} - y^{4} + x^{2} - y^{2}

(x + y) (x - y) (x^{2} + y^{2} + 1)

Solution steps

x^{4} - y^{4} + x^{2} - y^{2}

Factor

x^{4} - y^{4} : (x^{2} + y^{2}) (x + y) (x - y)

Factor

x^{2} - y^{2} : (x + y) (x - y)

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

Factor out common term

(x + y) (x - y) : (x + y) (x - y) (x^{2} + y^{2} + 1)

= (x + y) (x - y) (x^{2} + y^{2} + 1)

(4 + y)^{3}

\frac{( 5 a ^{m} \cdot ( 5 b ^{m} ) ^{2} )}{( ( a ^{2 m} ) ^{2} )}

y^{2} - 4 y + 4 - 4 x^{2}

55 x^{2} - 3 x + 2582 x^{2} - 9 x^{2} l

\frac{3 a ^{83} b ^{5}}{99}
