expand (x+2y-1)dx+3(x+2y)dy

expand

(x + 2 y - 1) d x + 3 (x + 2 y) d y

x d x + 2 y d x - d x + 3 x d y + 6 y d y

Solution steps

(x + 2 y - 1) d x + 3 (x + 2 y) d y

Expand

d x (x + 2 y - 1) : x d x + 2 y d x - d x

= x d x + 2 y d x - d x + 3 (x + 2 y) d y

Expand

3 d y (x + 2 y) : 3 x d y + 6 y d y

= x d x + 2 y d x - d x + 3 x d y + 6 y d y

1 - (\frac{1}{2}) - (\frac{3}{92}) \cdot (9 (1.6) - \frac{1. 6 ^{3}}{3})

(- 2 + 4 i)^{6}

A (2, 0) Y B (4, - 2)

(\frac{1}{2} x + 8) (\frac{3}{4} x + 5)

\frac{2 ( 31 + 4 10 )}{9}
