expand A(-2,1)B(5,-7)

expand

A (- 2, 1) B (5, - 7)

5 (- 2 \cdot 1,) A B, - 7 (- 2 \cdot 1,) A B

Solution steps

A (- 2, 1) B (5, - 7)

= (- 2 \cdot 1,) (5, - 7) A B

Apply the distributive law:

a (b - c) = ab - a c

a = A (- 2, 1) B, b = 5,, c = 7

= A (- 2, 1) B \cdot 5, - A (- 2, 1) B \cdot 7

= 5 (- 2 \cdot 1,) A B, - 7 (- 2 \cdot 1,) A B

(y + 1) d x + (4 x - 1) d y

\frac{1}{4 x ( 8 - 32 y + 56 z )}

\frac{1}{( x - 18 ) ^{2}}

a (- 1, 3) B (2, - 5) R \frac{3}{4}

(9 - 2 x)^{9} d x
