factor 25x^4y^4-91x^2y^4-36y^4

factor

25 x^{4} y^{4} - 91 x^{2} y^{4} - 36 y^{4}

y^{4} (25 x^{2} + 9) (x + 2) (x - 2)

Solution steps

25 x^{4} y^{4} - 91 x^{2} y^{4} - 36 y^{4}

Factor out common term

y^{4}

= y^{4} (25 x^{4} - 91 x^{2} - 36)

Factor

25 x^{4} - 91 x^{2} - 36 : (25 x^{2} + 9) (x + 2) (x - 2)

= y^{4} (25 x^{2} + 9) (x + 2) (x - 2)

(\frac{x + 1}{x}) (\frac{x - 1}{x}) (\frac{x ^{2} + 1}{( x ^{2} )})

\frac{( m ^{3} - m ^{4} )}{( m ^{2} - 8 m + 7 )}

x^{4} y^{3} + x^{5} y^{5}

x^{3} + 3 x + 3 x^{2} + 1

\frac{( 4 ( y + 1 ) )}{( ( y + 1 ) ( y - 1 ) )}
