Answer 1

Ответ:

$\displaystyle\\{\begin{array}{|c|c|c|c|c|c|c|c|c|c|c|c|}\cline{1-12} a&-2,5&-2&-1,5&-1&-0,5&0&0,5&1&1,5&2&2,5 \\ \cline{1-12} 4a^{2}&25&16&9&4&1&0&1&4&9&16&25 \\ \cline{1-12}-2a^{2}&-12,5&-8&-4,5&-2&-0,5&0&-0,5&-2&-4,5&-8&-12,5\\ \cline{1-12} \end{array}}$

Объяснение:

$4\cdot\left( -2,5 \right)^2 = 4\cdot6,25 = 25 \\ 4\cdot\left( -2 \right)^2 = 4\cdot4 = 16 \\ 4\cdot\left( -1,5 \right)^2 = 4\cdot2,25 = 9 \\ 4\cdot\left( -1 \right)^2 = 4\cdot1 = 4 \\ 4\cdot\left( -0,5 \right)^2 = 4\cdot0,25 = 1 \\ 4\cdot0^2 = 4\cdot0 = 0 \\ 4\cdot0,5^2 = 4\cdot0,25 = 1 \\ 4\cdot1^2 = 4\cdot1 = 4 \\ 4\cdot1,5^2 = 4\cdot2,25 = 9 \\ 4\cdot2^2 = 4\cdot4 = 16 \\ 4\cdot2,5^2 = 4\cdot6,25 = 25$

$- 2\cdot\left( -2,5 \right)^2= - 2\cdot6,25= - 12,5 \\ -2\cdot\left( -2 \right)^2= - 2\cdot4= - 8 \\ -2\cdot\left( -1,5 \right)^2= - 2\cdot2,25= - 4,5 \\ -2\cdot\left( -1 \right)^2= - 2\cdot1= - 2 \\ -2\cdot\left( -0,5 \right)^2= - 2\cdot0,25= - 0,5 \\ -2\cdot0^2= - 2\cdot0 = 0 \\ -2\cdot0,5^2= - 2\cdot0,25= - 0,5 \\ -2\cdot1^2= - 2\cdot1= - 2 \\ -2\cdot1,5^2= - 2\cdot2,25= - 4,5 \\ -2\cdot2^2= - 2\cdot4= - 8 \\ -2\cdot2,5^2= - 2\cdot6,25= - 12,5$
