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

Solution

expand

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

Solution

12 x^{3} + 8 x^{2} - 4 x

Solution steps

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

Apply the distributive law:

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

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

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

Simplify

4 x \cdot 3 x^{2} + 4 x \cdot 2 x + 4 x (- 1) : 12 x^{3} + 8 x^{2} - 4 x

= 12 x^{3} + 8 x^{2} - 4 x
