expand ((4-x)(4-x^2))2y

expand

((4 - x) (4 - x^{2})) 2 y

32 y - 8 x^{2} y - 8 x y + 2 x^{3} y

Solution steps

((4 - x) (4 - x^{2})) \cdot 2 y

Remove parentheses:

(a) = a

= (4 - x) (4 - x^{2}) \cdot 2 y

= 2 y (4 - x) (4 - x^{2})

Expand

(4 - x) (4 - x^{2}) : 16 - 4 x^{2} - 4 x + x^{3}

= 2 y (16 - 4 x^{2} - 4 x + x^{3})

Expand

2 y (16 - 4 x^{2} - 4 x + x^{3}) : 32 y - 8 x^{2} y - 8 x y + 2 x^{3} y

= 32 y - 8 x^{2} y - 8 x y + 2 x^{3} y

\frac{x ( x + 20 )}{20}

- 4 (3) (- 72)

sinh (a (t - b)) H (t - b)

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

1 + x^{2} + i - i
