expand (y+1)dx+(4x-1)dy

expand

(y + 1) d x + (4 x - 1) d y

y d x + d x + 4 x d y - d y

Solution steps

(y + 1) d x + (4 x - 1) d y

Expand

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

= y d x + d x + (4 x - 1) d y

Expand

d y (4 x - 1) : 4 x d y - d y

= y d x + d x + 4 x d y - d y

\frac{1}{4 x ( 8 - 32 y + 56 z )}

\frac{1}{( x - 18 ) ^{2}}

a (- 1, 3) B (2, - 5) R \frac{3}{4}

(9 - 2 x)^{9} d x

\frac{( ( n - 1 ) ( n - 2 ) )}{6}
