expand ,(w^2-5w-4)(7w^2-6w+2)

expand

(w^{2} - 5 w - 4) (7 w^{2} - 6 w + 2)

7 w^{4} - 41 w^{3} + 4 w^{2} + 14 w - 8

Solution steps

(w^{2} - 5 w - 4) (7 w^{2} - 6 w + 2)

Distribute parentheses

= w^{2} \cdot 7 w^{2} + w^{2} (- 6 w) + w^{2} \cdot 2 - 5 w \cdot 7 w^{2} - 5 w (- 6 w) - 5 w \cdot 2 - 4 \cdot 7 w^{2} - 4 (- 6 w) - 4 \cdot 2

Simplify

w^{2} \cdot 7 w^{2} + w^{2} (- 6 w) + w^{2} \cdot 2 - 5 w \cdot 7 w^{2} - 5 w (- 6 w) - 5 w \cdot 2 - 4 \cdot 7 w^{2} - 4 (- 6 w) - 4 \cdot 2 : 7 w^{4} - 41 w^{3} + 4 w^{2} + 14 w - 8

= 7 w^{4} - 41 w^{3} + 4 w^{2} + 14 w - 8

5 (- 2 u + 7 = 25)

\frac{( x + 1 ) ( x )}{10}

- \frac{2 ( 10368 W _{0} - 5 )}{5}

\forall x (x^{2} - x \neq = 1)

\frac{100}{( 1 - x \cdot 10 ) ^{2}}
