expand

- 2 y (1, - 1)

- 2 \cdot 1 \cdot y, 2 \cdot 1 \cdot y

Solution steps

- 2 y (1, - 1)

= - 2 (1, - 1) y

Apply the distributive law:

a (b - c) = ab - a c

a = - 2 y, b = 1,, c = 1

= - 2 y \cdot 1, - (- 2 y) \cdot 1

Apply minus-plus rules

- (- a) = a

= - 2 \cdot 1 \cdot y, 2 \cdot 1 \cdot y

- 3 π (32 - 11)

\frac{- 3 k + 320}{20 k ( 3 k + 10 )}

sin (2) (t + π)

\frac{1}{2} 5 y - 6 (= - y - 9)
