expand (w+7)(2w-2u-3)

expand

(w + 7) (2 w - 2 u - 3)

2 w^{2} - 2 w u + 11 w - 14 u - 21

Solution steps

(w + 7) (2 w - 2 u - 3)

Distribute parentheses

= w \cdot 2 w + w (- 2 u) + w (- 3) + 7 \cdot 2 w + 7 (- 2 u) + 7 (- 3)

Simplify

w \cdot 2 w + w (- 2 u) + w (- 3) + 7 \cdot 2 w + 7 (- 2 u) + 7 (- 3) : 2 w^{2} - 2 w u + 11 w - 14 u - 21

= 2 w^{2} - 2 w u + 11 w - 14 u - 21

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

(- 2 x^{3} \cdot z^{2})^{3} \cdot (3 x^{3} \cdot y \cdot z^{2})

(0.1 x - 0.2 y) (0.3 x + 0.1 y)

\frac{- 3}{x \cdot ( \frac{( 1 x - 1 )}{4} )}

3 x + 1 (4 x^{15}) - 13
