expand (2,-1)Y(-1,-13/7)

expand

(2, - 1) Y (- 1, - \frac{13}{7})

- 2 Y, 1, - 2 Y, \frac{13}{7} + 1 \cdot 1 \cdot Y, 1 \cdot \frac{13}{7}

Solution steps

(2, - 1) Y (- 1, - \frac{13}{7})

= (2, - 1) (- 1, - \frac{13}{7}) Y

Expand

(2, - 1) (- 1, - \frac{13}{7}) : - 2, 1, - 2, \frac{13}{7} + 1 \cdot 1, 1 \cdot \frac{13}{7}

= Y (- 2, 1, - 2, \frac{13}{7} + 1 \cdot 1, 1 \cdot \frac{13}{7})

Expand

Y (- 2, 1, - 2, \frac{13}{7} + 1 \cdot 1, 1 \cdot \frac{13}{7}) : - 2 Y, 1, - 2 Y, \frac{13}{7} + 1 \cdot 1 \cdot Y, 1 \cdot \frac{13}{7}

= - 2 Y, 1, - 2 Y, \frac{13}{7} + 1 \cdot 1 \cdot Y, 1 \cdot \frac{13}{7}
