expand (-1,1)y(5,-7/2)

expand

(- 1, 1) y (5, - \frac{7}{2})

5 (- 1 \cdot 1,) y, - \frac{7}{2} (- 1 \cdot 1,) y

Solution steps

(- 1, 1) y (5, - \frac{7}{2})

= (- 1 \cdot 1,) (5, - \frac{7}{2}) y

Apply the distributive law:

a (b - c) = ab - a c

a = (- 1, 1) y, b = 5,, c = \frac{7}{2}

= (- 1, 1) y \cdot 5, - (- 1, 1) y \frac{7}{2}

= 5 (- 1 \cdot 1,) y, - \frac{7}{2} (- 1 \cdot 1,) y

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

(8 hk + 5 e f) (8 hk - 5 e f)

(\frac{x + 1}{2})^{5}

\frac{6 ( 1 - cos ( x ) )}{x ^{2}}

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