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

Solution

expand

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

Solution

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

Solution steps

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

Apply the distributive law:

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

x (3 x^{2} + 2 x - 1) = x \cdot 3 x^{2} + x \cdot 2 x + x (- 1)

= x \cdot 3 x^{2} + x \cdot 2 x + x (- 1)

Simplify

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

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