expand (8,-2)(2x-5y=-12)

expand

(8, - 2) (2 x - 5 y = - 12)

8, 2 x - 8, 5 y = - 8, 12 - 2 \cdot 2 x + 2 \cdot 5 y = 2 \cdot 12

Solution steps

(8, - 2) (2 x - 5 y = - 12)

= (8, - 2) (2 x - 5 = y - 12)

Distribute parentheses

= 8, 2 x + 8, (- 5 y =) + 8, (- 12) + (- 2) \cdot 2 x + (- 2) (- 5 y =) + (- 2) (- 12)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

8, 2 x - 8, 5 y = - 8, 12 - 2 \cdot 2 x + 2 \cdot 5 y = 2 \cdot 12

A (4, 7) y B (5, - 1)

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

(e + 2 f)^{10}

(4 x + 1) (4 x + 1)^{'}

\frac{d}{d y} ((z) (x^{3} + y^{3} + z^{3} + 6 x y z - 1))
