expand

2 (x - 1) (x + 2)

2 x^{2} + 2 x - 4

Solution steps

2 (x - 1) (x + 2)

Expand

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

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

Apply the distributive law:

m (a + b + c) = ma + mb + m c

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

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

Multiply the numbers:

2 (- 2) = - 4

= 2 x^{2} + 2 x - 4

\frac{7}{- 5}

(2 x) (- x)

(x + 2 y)^{6}
