expand ,x(x+1)(x-4)

Solution

expand

x (x + 1) (x - 4)

Solution

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

Solution steps

x (x + 1) (x - 4)

Expand

x (x + 1) (x - 4) : x (x^{2} - 3 x - 4)

= x (x^{2} - 3 x - 4)

Apply the distributive law:

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

x (x^{2} - 3 x - 4) = x x^{2} + x (- 3 x) + x (- 4)

= x x^{2} + x (- 3 x) + x (- 4)

Simplify

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

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

Popular Examples

expand (8(-3x^2+2))/((x^2+2)^3)expand

\frac{8 ( - 3 x ^{2} + 2 )}{( x ^{2} + 2 ) ^{3}}

\frac{( n ( n + 1 ) )}{2}

expand (2s+10)/(s(s^2+6s+25))expand

\frac{2 s + 10}{s ( s ^{2} + 6 s + 25 )}
