expand x(2x+1)(x-3)

Solution

expand

x (2 x + 1) (x - 3)

Solution

2 x^{3} - 5 x^{2} - 3 x

Solution steps

x (2 x + 1) (x - 3)

Expand

x (2 x + 1) (x - 3) : x (2 x^{2} - 5 x - 3)

= x (2 x^{2} - 5 x - 3)

Apply the distributive law:

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

x (2 x^{2} - 5 x - 3) = x \cdot 2 x^{2} + x (- 5 x) + x (- 3)

= x \cdot 2 x^{2} + x (- 5 x) + x (- 3)

Simplify

x \cdot 2 x^{2} + x (- 5 x) + x (- 3) : 2 x^{3} - 5 x^{2} - 3 x

= 2 x^{3} - 5 x^{2} - 3 x
