expand A(-1,2)B(2,-1)

expand

A (- 1, 2) B (2, - 1)

2 (- 1 \cdot 2,) A B, - 1 \cdot (- 1 \cdot 2,) A B

Solution steps

A (- 1, 2) B (2, - 1)

= (- 1 \cdot 2,) (2, - 1) A B

Apply the distributive law:

a (b - c) = ab - a c

a = A (- 1, 2) B, b = 2,, c = 1

= A (- 1, 2) B \cdot 2, - A (- 1, 2) B \cdot 1

= 2 (- 1 \cdot 2,) A B, - 1 \cdot (- 1 \cdot 2,) A B

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

(π - 4)^{2}

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

(21 x - 6 y = 5, 4) - (9 + y = 3.5 x)
