expand x+2((x+1)(x-1))

expand

x + 2 ((x + 1) (x - 1))

2 x^{2} + x - 2

Solution steps

x + 2 ((x + 1) (x - 1))

Remove parentheses:

(a) = a

= x + 2 (x + 1) (x - 1)

Expand

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

= x + 2 x^{2} - 2

Rewrite in standard form

= 2 x^{2} + x - 2

\frac{( x - 3 ) ( a + 2 )}{5}

\frac{( x - 9 ) ( x + 7 )}{x ^{2} + 4}

- 5 (1 - 5 x) + 5 (- 8 x - 2 = - 4 x - 8 x)

A (4, - 3, 1) b (- 2, 4, - 1)

(e^{x} + 1) (e^{x} + 2)
