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

expand

(1, - 5) y (- 2, 1)

1 \cdot (- 2 \cdot 1,) y, - 5 (- 2 \cdot 1,) y

Solution steps

(1, - 5) y (- 2, 1)

= (1, - 5) (- 2 \cdot 1,) y

Apply the distributive law:

a (b - c) = ab - a c

a = y (- 2, 1), b = 1,, c = 5

= y (- 2, 1) \cdot 1, - y (- 2, 1) \cdot 5

= 1 \cdot (- 2 \cdot 1,) y, - 5 (- 2 \cdot 1,) y

sin (w (t - a))

\frac{\partial}{\partial x} ((z) (x^{2} + y^{2}))

x^{\frac{1}{3}} (x^{2} - 21)

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

\frac{5}{2} + \frac{2 ( 4 2 - 2 )}{3}
