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

Solution

expand

x (x - 3) (x - 4)

Solution

x^{3} - 7 x^{2} + 12 x

Solution steps

x (x - 3) (x - 4)

Expand

x (x - 3) (x - 4) : x (x^{2} - 7 x + 12)

= x (x^{2} - 7 x + 12)

Apply the distributive law:

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

x (x^{2} - 7 x + 12) = x x^{2} + x (- 7 x) + x \cdot 12

= x x^{2} + x (- 7 x) + x \cdot 12

Simplify

x x^{2} + x (- 7 x) + x \cdot 12 : x^{3} - 7 x^{2} + 12 x

= x^{3} - 7 x^{2} + 12 x
