Answer 1

Ответ:

$-10x^2(x^2+2,3)+\frac{20x^4(-16x^2-24)}{-8} = \\ - 10 {x}^{2} \times {x}^{2} + ( - 10 {x}^{2} ) \times 2.3 + \\ \frac{20 {x}^{4} \times ( - 13 {x}^{2}) + 20 {x}^{4} \times ( - 24) }{ - 8} = \\ - 10 {x}^{4} - 23 {x}^{2} + \frac{ - 260 {x}^{6} - 480 {x}^{4} }{ - 8} = \\ - 10 {x}^{4} - 23 {x}^{2} + ( \frac{ - 260 {x}^{6} }{ - 8} + ( \frac{ - 480 {x}^{4} }{ - 8} ) = \\ - 10 {x}^{4} - 23 {x}^{2} + 32.5 {x}^{6} + 60 {x}^{4} = \\ 32.5 {x}^{6} + 50 {x}^{4} - 23 {x}^{2}$
