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

expand

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

12 x^{3} + 19 x^{2} - 4 x - 2

Solution steps

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

Distribute parentheses

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

Simplify

4 x \cdot 3 x^{2} + 4 x \cdot 4 x + 4 x (- 2) + 1 \cdot 3 x^{2} + 1 \cdot 4 x + 1 \cdot (- 2) : 12 x^{3} + 19 x^{2} - 4 x - 2

= 12 x^{3} + 19 x^{2} - 4 x - 2

1 \times 2

- \frac{36}{49}
