expand-2x(6x^2+7x+2)

expand

- 2 x (6 x^{2} + 7 x + 2)

- 12 x^{3} - 14 x^{2} - 4 x

Solution steps

- 2 x (6 x^{2} + 7 x + 2)

Apply the distributive law:

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

- 2 x (6 x^{2} + 7 x + 2) = - 2 x \cdot 6 x^{2} - 2 x \cdot 7 x - 2 x \cdot 2

= - 2 x \cdot 6 x^{2} - 2 x \cdot 7 x - 2 x \cdot 2

Simplify

- 2 x \cdot 6 x^{2} - 2 x \cdot 7 x - 2 x \cdot 2 : - 12 x^{3} - 14 x^{2} - 4 x

= - 12 x^{3} - 14 x^{2} - 4 x

6 x^{3} - 9 x^{2} + 4 x - 6

1 \times 1 0^{5}

4 x - 3 x - 2 x

144 + - 98 - 121 + - 2

(\frac{2}{2})^{2} + (\frac{2}{2})^{2}
