expand x(x+6)(x+3)

Solution

expand

x (x + 6) (x + 3)

Solution

x^{3} + 9 x^{2} + 18 x

Solution steps

x (x + 6) (x + 3)

Expand

x (x + 6) (x + 3) : x (x^{2} + 9 x + 18)

= x (x^{2} + 9 x + 18)

Apply the distributive law:

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

x (x^{2} + 9 x + 18) = x x^{2} + x \cdot 9 x + x \cdot 18

= x x^{2} + x \cdot 9 x + x \cdot 18

Simplify

x x^{2} + x \cdot 9 x + x \cdot 18 : x^{3} + 9 x^{2} + 18 x

= x^{3} + 9 x^{2} + 18 x
