expand (8x,2y)(-4x-y,2x-y)

expand

(8 x, 2 y) (- 4 x - y, 2 x - y)

- 4 x (8 \cdot 2, x y) - y (8 \cdot 2, x y), 2 x - y (8 \cdot 2, x y)

Solution steps

(8 x, 2 y) (- 4 x - y, 2 x - y)

= (8 \cdot 2, x y) (- 4 x - 2, x y - y)

Distribute parentheses

= (8 x, 2 y) (- 4 x) + (8 x, 2 y) (- y, 2 x) + (8 x, 2 y) (- y)

Apply minus-plus rules

+ (- a) = - a

= - 4 x (8 \cdot 2, x y) - y (8 \cdot 2, x y), 2 x - y (8 \cdot 2, x y)

\frac{y ( y ^{2} + 2 x ^{2} )}{2 x ( x ^{2} + y ^{2} )}

\frac{( 2 ( 6 - 2 x ) ^{3} )}{27}

\frac{6 s ^{2} + 5}{s ( 2 s ^{2} + 4 s + 1 )}

\frac{2}{3} (x - 5)^{\frac{3}{2}}

\frac{( 3 x + 5 y ) ^{2}}{2}
