\[(x - 5)^2 - (6x)^2\]
\[((x - 5) - 6x)((x - 5) + 6x) = (x - 5 - 6x)(x - 5 + 6x) = (-5x - 5)(7x - 5)\]
\[-5(x + 1)(7x - 5)\]
Ответ: -5(x + 1)(7x - 5)
\[x^2 - 4y^2 = (x - 2y)(x + 2y)\]
\[(x - 2y)(x + 2y) - (x - 2y) = (x - 2y)((x + 2y) - 1) = (x - 2y)(x + 2y - 1)\]
Ответ: (x - 2y)(x + 2y - 1)
\[(3x)^3 + (y^2)^3\]
\[(3x + y^2)((3x)^2 - (3x)(y^2) + (y^2)^2) = (3x + y^2)(9x^2 - 3xy^2 + y^4)\]
Ответ: (3x + y²)(9x² - 3xy² + y⁴)
