(2x-1)^2 = 4x^2 - 4x + 1(x + 3y)^2 = x^2 + 6xy + 9y^2(3x - 1)^2 = 9x^2 - 6x + 1(2x - 3y)^2 = 4x^2 - 12xy + 9y^2
Итак, многочлен будет:4x^2 - 4x + 1 x^2 + 6xy + 9y^2 9x^2 - 6x + 1 * 4x^2 - 12xy + 9y^2
(2x-1)^2 = 4x^2 - 4x + 1
(x + 3y)^2 = x^2 + 6xy + 9y^2
(3x - 1)^2 = 9x^2 - 6x + 1
(2x - 3y)^2 = 4x^2 - 12xy + 9y^2
Итак, многочлен будет:
4x^2 - 4x + 1 x^2 + 6xy + 9y^2 9x^2 - 6x + 1 * 4x^2 - 12xy + 9y^2
