expand (a^4-3b^2+1)/((a^2+b-1)(a^2-b-1))

expand

\frac{a ^{4} - 3 b ^{2} + 1}{( a ^{2} + b - 1 ) ( a ^{2} - b - 1 )}

\frac{a ^{4} - 3 b ^{2} + 1}{a ^{4} - 2 a ^{2} - b ^{2} + 1}

Solution steps

\frac{a ^{4} - 3 b ^{2} + 1}{( a ^{2} + b - 1 ) ( a ^{2} - b - 1 )}

Expand

(a^{2} + b - 1) (a^{2} - b - 1) : a^{4} - 2 a^{2} - b^{2} + 1

= \frac{a ^{4} - 3 b ^{2} + 1}{a ^{4} - 2 a ^{2} - b ^{2} + 1}

(2 a + c - d) y (2 a + c - e + 3)

\frac{15}{x ( x + 4 )}

(\frac{a}{x - 2} + \frac{b}{x + 2}) (x - 2) (x + 2)

p^{\frac{2}{3}} (p^{\frac{1}{3}} + 2 p^{\frac{7}{3}})

(x + \frac{4}{5}) (x - \frac{2}{5})
