expand (t^2+1)/((1+t)^3)

expand

\frac{t ^{2} + 1}{( 1 + t ) ^{3}}

\frac{t ^{2} + 1}{1 + 3 t + 3 t ^{2} + t ^{3}}

Solution steps

\frac{t ^{2} + 1}{( 1 + t ) ^{3}}

(1 + t)^{3} = 1 + 3 t + 3 t^{2} + t^{3}

= \frac{t ^{2} + 1}{1 + 3 t + 3 t ^{2} + t ^{3}}

- 5 (2 - 3)

(- 3 + 5 i, - 3 + 3 i, 10 - 3 i) \cdot (- 3 - 2 i, - 4 - 3 i, 4 + 2 i)

x_{1} (x^{4} = 2 x + 1)

\frac{1}{x ^{\frac{3}{4}} ( x + 1 - x )}

3 (x - 2)^{2}
