(x + 2) (x + 3) (x + 4) : x^{3} + 9 x^{2} + 26 x + 24

= \frac{2 x ^{2} + 9 x + 7}{x ^{3} + 9 x ^{2} + 26 x + 24}

e x p an d (y + x^{2} + y^{2}) d x

e x p an d (4 y - e^{y} sin (x)) + i (4 y - e^{y} sin (x) + c)

e x p an d \frac{( x ^{2} - 3 x - 4 ) ( x + 1 )}{( x - 1 ) ( x ^{2} + 2 x - 3 )}

e x p an d \frac{( y - 3 ) ^{2}}{4}

e x p an d (3 - x - 1) (6 - x - 2)
