expand (2xy+x^2-1)dy

expand

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

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

Solution steps

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

Distribute parentheses

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

Apply minus-plus rules

+ (- a) = - a

= 2 x y d y + x^{2} d y - 1 \cdot d y

Multiply:

1 \cdot d y = d y

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

a (e^{- k x} + e^{k x})

\frac{3 ( 8 + x )}{2}

\frac{2}{( 2 - x ) ^{3}}

\frac{( 6 a + 7 b ) ( a - 7 b )}{b ( 6 ab + 7 )}

t (x = 5 t + 3)
