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

expand

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

- 2 x^{2} b^{2} - 3 b x^{2} - x^{2} - 2 b^{2} - 2 b

Solution steps

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

Simplify

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

= - x^{2} (b + 1) (2 b + 1) - 2 b (b + 1)

Expand

- x^{2} (b + 1) (2 b + 1) : - 2 x^{2} b^{2} - 3 b x^{2} - x^{2}

= - 2 x^{2} b^{2} - 3 b x^{2} - x^{2} - 2 b (b + 1)

Expand

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

= - 2 x^{2} b^{2} - 3 b x^{2} - x^{2} - 2 b^{2} - 2 b

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

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