expand 2x(4x^2+3x-1)

Solution

expand

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

Solution

8 x^{3} + 6 x^{2} - 2 x

Solution steps

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

Apply the distributive law:

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

2 x (4 x^{2} + 3 x - 1) = 2 x \cdot 4 x^{2} + 2 x \cdot 3 x + 2 x (- 1)

= 2 x \cdot 4 x^{2} + 2 x \cdot 3 x + 2 x (- 1)

Simplify

2 x \cdot 4 x^{2} + 2 x \cdot 3 x + 2 x (- 1) : 8 x^{3} + 6 x^{2} - 2 x

= 8 x^{3} + 6 x^{2} - 2 x
