expand ((1-a)^2)/(a^2+2a+1)

expand

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

\frac{1 - 2 a + a ^{2}}{a ^{2} + 2 a + 1}

Solution steps

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

(1 - a)^{2} = 1 - 2 a + a^{2}

= \frac{1 - 2 a + a ^{2}}{a ^{2} + 2 a + 1}

cos (x) sin (x) (1 + cos (x))

(5 e - 5 t sin (2 π t) + 2 π (1 - e - 5 t) cos (2 π t))^{2}

x^{2 (2 n + 2)}

e^{4 (1 + 2 t)}

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