expand (7w+5)(7w-7u+3)

expand

(7 w + 5) (7 w - 7 u + 3)

49 w^{2} - 49 w u + 56 w - 35 u + 15

Solution steps

(7 w + 5) (7 w - 7 u + 3)

Distribute parentheses

= 7 w \cdot 7 w + 7 w (- 7 u) + 7 w \cdot 3 + 5 \cdot 7 w + 5 (- 7 u) + 5 \cdot 3

Simplify

7 w \cdot 7 w + 7 w (- 7 u) + 7 w \cdot 3 + 5 \cdot 7 w + 5 (- 7 u) + 5 \cdot 3 : 49 w^{2} - 49 w u + 56 w - 35 u + 15

= 49 w^{2} - 49 w u + 56 w - 35 u + 15

4 x + (\frac{4 3 x}{48})

a^{2} + 2 a - b^{2} + 1

j - 5 + (2 - j^{3}) - 1

\frac{sin ^{4} ( x )}{cos ^{4} ( x )}

(0.417 y)^{\frac{2}{3}}
