expand a(5,-2)b(-1,2)

expand

a (5, - 2) b (- 1, 2)

5 (- 1 \cdot 2,) ab, - 2 (- 1 \cdot 2,) ab

Solution steps

a (5, - 2) b (- 1, 2)

= (5, - 2) (- 1 \cdot 2,) ab

Apply the distributive law:

a (b - c) = ab - a c

a = ab (- 1, 2), b = 5,, c = 2

= ab (- 1, 2) \cdot 5, - ab (- 1, 2) \cdot 2

= 5 (- 1 \cdot 2,) ab, - 2 (- 1 \cdot 2,) ab

(x + 2) \cdot e^{x - 1}

\frac{6 s + 7}{( s ^{2} + 6 s + 25 ) ^{2}}

(x + 2) (x + 3) (x - 3)

(sec (x) - tan (x)) (csc (x) - 1)

\frac{d}{d t} ((x) (e^{t} - t))
