expand (-x+4)(3x^2-2x-7)

expand

(- x + 4) (3 x^{2} - 2 x - 7)

- 3 x^{3} + 14 x^{2} - x - 28

Solution steps

(- x + 4) (3 x^{2} - 2 x - 7)

Distribute parentheses

= - x \cdot 3 x^{2} - x (- 2 x) - x (- 7) + 4 \cdot 3 x^{2} + 4 (- 2 x) + 4 (- 7)

Simplify

- x \cdot 3 x^{2} - x (- 2 x) - x (- 7) + 4 \cdot 3 x^{2} + 4 (- 2 x) + 4 (- 7) : - 3 x^{3} + 14 x^{2} - x - 28

= - 3 x^{3} + 14 x^{2} - x - 28

5 \times \frac{3}{4}

+ t^{3} + 64

- \frac{1}{3} \times (- 3)

+ 100000 0^{\frac{1}{6}}

\frac{9 + 3 ^{2} \times \frac{36}{2}}{9}
