expand a(2,-1,1)+b(1,-6,2)

expand

a (2, - 1, 1) + b (1, - 6, 2)

2 a, - 1 \cdot a, 1 + 1 \cdot b, - 6 b, 2

Solution steps

a (2, - 1, 1) + b (1, - 6, 2)

= (2, - 1 \cdot 1,) a + (1, - 6 \cdot 2,) b

Expand

a (2, - 1, 1) : 2 a, - 1 \cdot a, 1

= 2 a, - 1 \cdot a, 1 + b (1, - 6, 2)

Expand

b (1, - 6, 2) : 1 \cdot b, - 6 b, 2

= 2 a, - 1 \cdot a, 1 + 1 \cdot b, - 6 b, 2

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

(1 + x^{2} - x 1 + x^{2}) (1 + x^{2})

8 (e^{- 0.4 t} - e^{- 0.6 t})

(3 x + 8 y - 24 = 0,) (9 x - 2 y - 18 = 0)

(7) (2 x - y = 13)
