expand (7x^2-6x-6)(2x-4)

expand

(7 x^{2} - 6 x - 6) (2 x - 4)

14 x^{3} - 40 x^{2} + 12 x + 24

Solution steps

(7 x^{2} - 6 x - 6) (2 x - 4)

Distribute parentheses

= 7 x^{2} \cdot 2 x + 7 x^{2} (- 4) - 6 x \cdot 2 x - 6 x (- 4) - 6 \cdot 2 x - 6 (- 4)

Simplify

7 x^{2} \cdot 2 x + 7 x^{2} (- 4) - 6 x \cdot 2 x - 6 x (- 4) - 6 \cdot 2 x - 6 (- 4) : 14 x^{3} - 40 x^{2} + 12 x + 24

= 14 x^{3} - 40 x^{2} + 12 x + 24

(100 - x)^{2}

\frac{8 + i}{12 - 4 i}
