expand

a (2, - 1) b (- 1, 3)

2 (- 1 \cdot 3,) ab, - 1 \cdot (- 1 \cdot 3,) ab

Solution steps

a (2, - 1) b (- 1, 3)

= (2, - 1) (- 1 \cdot 3,) ab

Apply the distributive law:

a (b - c) = ab - a c

a = ab (- 1, 3), b = 2,, c = 1

= ab (- 1, 3) \cdot 2, - ab (- 1, 3) \cdot 1

= 2 (- 1 \cdot 3,) ab, - 1 \cdot (- 1 \cdot 3,) ab

(x + 2) + (4 x - 4)

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

(x + y) d x + (x - y) d y
