factor (x^2-1)/(x^2-4)

factor

\frac{x ^{2} - 1}{x ^{2} - 4}

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

Solution steps

\frac{x ^{2} - 1}{x ^{2} - 4}

Factor

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

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

Factor

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

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

r s^{2} + p s^{2} - 4 r - 4 p

e x + 2 x

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

\frac{4 - x ^{2}}{x ^{3} - x}
