expand x(x+4)(x-3)

Solution

expand

x (x + 4) (x - 3)

Solution

x^{3} + x^{2} - 12 x

Solution steps

x (x + 4) (x - 3)

Expand

x (x + 4) (x - 3) : x (x^{2} + x - 12)

= x (x^{2} + x - 12)

Apply the distributive law:

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

x (x^{2} + x - 12) = x x^{2} + xx + x (- 12)

= x x^{2} + xx + x (- 12)

Simplify

x x^{2} + xx + x (- 12) : x^{3} + x^{2} - 12 x

= x^{3} + x^{2} - 12 x
