expand (1,-2)y(-4,1)

expand

(1, - 2) y (- 4, 1)

1 \cdot (- 4 \cdot 1,) y, - 2 (- 4 \cdot 1,) y

Solution steps

(1, - 2) y (- 4, 1)

= (1, - 2) (- 4 \cdot 1,) y

Apply the distributive law:

a (b - c) = ab - a c

a = y (- 4, 1), b = 1,, c = 2

= y (- 4, 1) \cdot 1, - y (- 4, 1) \cdot 2

= 1 \cdot (- 4 \cdot 1,) y, - 2 (- 4 \cdot 1,) y

\frac{( x ^{2} - 49 ) ( x + 9 )}{x ^{2} + 2 x - 24}

(- t) (e^{- t} - e^{2 t})

1 (0 - 3) (- x - 3 = y)

(x^{3} + 4)^{2} + x ln (2 x)
