expand x(x+1)(x+3)

Solution

expand

x (x + 1) (x + 3)

Solution

x^{3} + 4 x^{2} + 3 x

Solution steps

x (x + 1) (x + 3)

Expand

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

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

Apply the distributive law:

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

x (x^{2} + 4 x + 3) = x x^{2} + x \cdot 4 x + x \cdot 3

= x x^{2} + x \cdot 4 x + x \cdot 3

Simplify

x x^{2} + x \cdot 4 x + x \cdot 3 : x^{3} + 4 x^{2} + 3 x

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