expand [(x-4)(2x+1)]x

Solution

expand

[(x - 4) (2 x + 1)] x

Solution

2 x^{3} - 7 x^{2} - 4 x

Solution steps

((x - 4) (2 x + 1)) x

Remove parentheses:

(a) = a

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

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

Expand

(x - 4) (2 x + 1) : 2 x^{2} - 7 x - 4

= x (2 x^{2} - 7 x - 4)

Expand

x (2 x^{2} - 7 x - 4) : 2 x^{3} - 7 x^{2} - 4 x

= 2 x^{3} - 7 x^{2} - 4 x
