Solution steps

(x - 4) (4 x^{2} - 8 x + 7)

Distribute parentheses

= x \cdot 4 x^{2} + x (- 8 x) + x \cdot 7 - 4 \cdot 4 x^{2} - 4 (- 8 x) - 4 \cdot 7

Simplify

x \cdot 4 x^{2} + x (- 8 x) + x \cdot 7 - 4 \cdot 4 x^{2} - 4 (- 8 x) - 4 \cdot 7 : 4 x^{3} - 24 x^{2} + 39 x - 28

= 4 x^{3} - 24 x^{2} + 39 x - 28
