expand 1/((ar+1)(ar+a+1))

expand

\frac{1}{( a r + 1 ) ( a r + a + 1 )}

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

Solution steps

\frac{1}{( a r + 1 ) ( a r + a + 1 )}

Expand

(a r + 1) (a r + a + 1) : a^{2} r^{2} + a^{2} r + 2 a r + a + 1

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

u (5, 1) y v (3, - 2)

e^{t} (cos (4 t) - 2 sin (4 t))

\frac{( x + y ) ^{2}}{x}

\frac{e ^{- 1.5 s}}{s ( s + 1 )}

\frac{2 s + 3}{( s + 1 ) ( s + 2 )}
