expand (-2+3d=6,)(2n-2d=4)

expand

(- 2 + 3 d = 6,) (2 n - 2 d = 4)

- 4 n + 4 d = 4

Solution steps

(- 2 + 3 d = 6,) (2 n - 2 d = 4)

= (- 2 + 3 \cdot 6 =, d) (2 n - 2 \cdot 4 = d)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = - 2, b = 3 d = 6,, c = 2 n, d = - 2 d = 4

(- 2) \cdot 2 n + (- 2) (- 2 d = 4) + 3 d = 6, 2 n + 3 d = 6, (- 2 d = 4)

Apply minus-plus rules

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

- 2 \cdot 2 n + 2 \cdot 2 d = 4 + 3 d = 6, 2 n - 3 d = 6, 2 d = 4

Expand

- 2 \cdot 2 n + 2 \cdot 2 d : - 4 n + 4 d

- 4 n + 4 d = 4

(3 = 6 - \frac{15 + 18}{9}) \cdot 9

\frac{10 x + 25}{( x - 1 ) ( x - 2 )}

\frac{x ^{2} - 4}{x + 2}

(6 x - 2 y) (6 - 2 y^{'} (x))

\frac{2 b x}{( a + b x ) ^{2}}
