expand (2x^2-3x+2x^4-5)*(-5x-x^2-4+3x^4)

expand

(2 x^{2} - 3 x + 2 x^{4} - 5) \cdot (- 5 x - x^{2} - 4 + 3 x^{4})

6 x^{8} + 4 x^{6} - 19 x^{5} - 25 x^{4} - 7 x^{3} + 12 x^{2} + 37 x + 20

Solution steps

(2 x^{2} - 3 x + 2 x^{4} - 5) (- 5 x - x^{2} - 4 + 3 x^{4})

Distribute parentheses

= 2 x^{2} (- 5 x) + 2 x^{2} (- x^{2}) + 2 x^{2} (- 4) + 2 x^{2} \cdot 3 x^{4} - 3 x (- 5 x) - 3 x (- x^{2}) - 3 x (- 4) - 3 x \cdot 3 x^{4} + 2 x^{4} (- 5 x) + 2 x^{4} (- x^{2}) + 2 x^{4} (- 4) + 2 x^{4} \cdot 3 x^{4} - 5 (- 5 x) - 5 (- x^{2}) - 5 (- 4) - 5 \cdot 3 x^{4}

Simplify

2 x^{2} (- 5 x) + 2 x^{2} (- x^{2}) + 2 x^{2} (- 4) + 2 x^{2} \cdot 3 x^{4} - 3 x (- 5 x) - 3 x (- x^{2}) - 3 x (- 4) - 3 x \cdot 3 x^{4} + 2 x^{4} (- 5 x) + 2 x^{4} (- x^{2}) + 2 x^{4} (- 4) + 2 x^{4} \cdot 3 x^{4} - 5 (- 5 x) - 5 (- x^{2}) - 5 (- 4) - 5 \cdot 3 x^{4} : 6 x^{8} + 4 x^{6} - 19 x^{5} - 25 x^{4} - 7 x^{3} + 12 x^{2} + 37 x + 20

= 6 x^{8} + 4 x^{6} - 19 x^{5} - 25 x^{4} - 7 x^{3} + 12 x^{2} + 37 x + 20

(- 9 w^{3} u)^{2}

8 (2 x) (- 6)

f (x) 4 x^{2} + 100 x - 60

3^{x + 2} + 3^{- x}

(4 x^{10})^{\frac{3}{2}}
