Question

Запишите в виде многочлена следующие выражения
(0,1x-0,2y)^2
(0,4a+0,5b)^2
(-3x+6y)^2
(7a-b)^2
(-a-8b)^2
(x-9y)^2

Answer 1

$1)(0.1x - 0.2y) {}^{2} \ ( frac{1}{10} x - frac{1}{5} y) {}^{2} \ \ frac{1}{100} x { }^{2} - frac{1}{25} xy + frac{1}{25} y {}^{2}$
$1)(0.1x - 0.2y) {}^{2} \ ( frac{1}{10} x - frac{1}{5} y) {}^{2} \ \ frac{1}{100} x { }^{2} - frac{1}{25} xy + frac{1}{25} y {}^{2} \ \ 2)(0.4a + 0.5b) {}^{2} \ \ ( frac{2}{5} a + frac{1}{2} b) \ \ frac{4}{25} a {}^{2} + frac{2}{5} ab + frac{1}{4} b {}^{2} \ \ 3)( - 3x + 6y) {}^{2} \ ( 6y - 3x) {}^{2} \ (6y) {}^{2} - 2 times 6y times 3x + (3x) {}^{2} \ 36y {}^{2} - 36xy + 9x {}^{2} \ \ 4)(7a - b) {}^{2} \ (7a) {}^{2} - 2 times 7ab + b {}^{2} \ 49a {}^{2} - 14ab + b {}^{2} \ \ 5)( - a - 8b) {}^{2} \ ( - a) {}^{2} + 16ab + 64b {}^{2} \ a {}^{2} + 16ab + 64b {}^{2} \ \ 6) (x - 9y) {}^{2} \ x {}^{2} - 2x times 9y + (9y) {}^{2} \ x {}^{2} - 18xy + 81y {}^{2}$
