expand (-y+2)(x+5/2)-(y+1)(-x-1/2)

expand

(- y + 2) (x + \frac{5}{2}) - (y + 1) (- x - \frac{1}{2})

\frac{- 4 y + 6 x + 1}{2} + 5

Solution steps

(- y + 2) (x + \frac{5}{2}) - (y + 1) (- x - \frac{1}{2})

Expand

(- y + 2) (x + \frac{5}{2}) : - y x + \frac{4 x - 5 y}{2} + 5

= - y x + \frac{4 x - 5 y}{2} + 5 - (y + 1) (- x - \frac{1}{2})

Expand

- (y + 1) (- x - \frac{1}{2}) : y x - \frac{- 2 x - y - 1}{2}

= - y x + \frac{4 x - 5 y}{2} + 5 + y x - \frac{- 2 x - y - 1}{2}

Simplify

- y x + \frac{4 x - 5 y}{2} + 5 + y x - \frac{- 2 x - y - 1}{2} : \frac{- 4 y + 6 x + 1}{2} + 5

= \frac{- 4 y + 6 x + 1}{2} + 5

(4 + 3 x) x^{3} + e^{3 x} \cdot 3 x^{4} + 4

\frac{4}{( 1 - x ) ^{3}}

\frac{( ( x + 1 ) ^{2} - π ^{2} )}{x ^{2} - π ^{2}}

\frac{π ( - 7 S + 84 π )}{14 π}

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