expand (y^2+1)dx+(x^2+1)dy

expand

(y^{2} + 1) d x + (x^{2} + 1) d y

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

Solution steps

(y^{2} + 1) d x + (x^{2} + 1) d y

Expand

d x (y^{2} + 1) : y^{2} d x + d x

= y^{2} d x + d x + (x^{2} + 1) d y

Expand

d y (x^{2} + 1) : x^{2} d y + d y

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

r e^{100} (x - 4)^{2}

\frac{x ( 4 x - 13 )}{( x + 3 ) ( x - 2 )}

x \cdot (x^{2} - 12 x + 20 = 0)

(x)^{2} + (y - 1)^{2}
