factor 77x^4-72x^2-77

factor

77 x^{4} - 72 x^{2} - 77

(11 x^{2} + 7) (7 x^{2} - 11)

Solution steps

77 x^{4} - 72 x^{2} - 77

Let

u = x^{2}

= 77 u^{2} - 72 u - 77

Factor

77 u^{2} - 72 u - 77 : (11 u + 7) (7 u - 11)

= (11 u + 7) (7 u - 11)

Substitute back

u = x^{2}

= (11 x^{2} + 7) (7 x^{2} - 11)

(2 x - 3 y - 4 z)^{3}

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

\frac{( 6 y - 6 x )}{2}

\frac{sin ( x ) + ( cos ^{2} ( x ) )}{sin ( x )}

\frac{( 1 + a ^{7} )}{( 1 + a )}
