expand ((7x^2-56x+105)*(-3x^2+108))x

expand

((7 x^{2} - 56 x + 105) \cdot (- 3 x^{2} + 108)) x

- 21 x^{5} + 168 x^{4} + 441 x^{3} - 6048 x^{2} + 11340 x

Solution steps

((7 x^{2} - 56 x + 105) (- 3 x^{2} + 108)) x

Remove parentheses:

(a) = a

= (7 x^{2} - 56 x + 105) (- 3 x^{2} + 108) x

= x (7 x^{2} - 56 x + 105) (- 3 x^{2} + 108)

Expand

(7 x^{2} - 56 x + 105) (- 3 x^{2} + 108) : - 21 x^{4} + 168 x^{3} + 441 x^{2} - 6048 x + 11340

= x (- 21 x^{4} + 168 x^{3} + 441 x^{2} - 6048 x + 11340)

Expand

x (- 21 x^{4} + 168 x^{3} + 441 x^{2} - 6048 x + 11340) : - 21 x^{5} + 168 x^{4} + 441 x^{3} - 6048 x^{2} + 11340 x

= - 21 x^{5} + 168 x^{4} + 441 x^{3} - 6048 x^{2} + 11340 x

- \frac{1}{( 3 + s ) ^{2} ( 1 + s )}
