expand (x^2+3xy)dx+(x^2+y^2)dy

expand

(x^{2} + 3 x y) d x + (x^{2} + y^{2}) d y

x^{2} d x + 3 x y d x + x^{2} d y + y^{2} d y

Solution steps

(x^{2} + 3 x y) d x + (x^{2} + y^{2}) d y

Expand

d x (x^{2} + 3 x y) : x^{2} d x + 3 x y d x

= x^{2} d x + 3 x y d x + (x^{2} + y^{2}) d y

Expand

d y (x^{2} + y^{2}) : x^{2} d y + y^{2} d y

= x^{2} d x + 3 x y d x + x^{2} d y + y^{2} d y

(1 + x + y) e^{x y}

- \frac{2 ( 11 + 489 )}{23}

\frac{d}{d t} ((x) (- 2 x (x - 8)))

\frac{2 ( 2 y + 19 )}{3}

\frac{50}{2}
