expand 3x(2x^2+5x-4)

Solution

expand

3 x (2 x^{2} + 5 x - 4)

Solution

6 x^{3} + 15 x^{2} - 12 x

Solution steps

3 x (2 x^{2} + 5 x - 4)

Apply the distributive law:

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

3 x (2 x^{2} + 5 x - 4) = 3 x \cdot 2 x^{2} + 3 x \cdot 5 x + 3 x (- 4)

= 3 x \cdot 2 x^{2} + 3 x \cdot 5 x + 3 x (- 4)

Simplify

3 x \cdot 2 x^{2} + 3 x \cdot 5 x + 3 x (- 4) : 6 x^{3} + 15 x^{2} - 12 x

= 6 x^{3} + 15 x^{2} - 12 x
