Answer 1

Ответ:

$1)ax + ay - x - y = a(x + y) - 1(x + y) = (a - 1)(x + y)$

$2)ab - 8a - bx + 8x = b(a -x) - 8(a - x) = (b - 8)(a - x)$

$3)7a - 7b + an - bn = 7(a - b) + n(a - b) = (7 + n)(a - b)$

$4)xy + 2y + 2x + 4 = y(x + 2) + 2(x + 2) = (y + 2)(x + 2)$

$5) {y}^{2} a - {y}^{2} b + {xa}^{2} - {x}^{2}b = {y}^{2} (a - b) + {x}^{2}( a - b) = ( {y}^{2} + {x}^{2} )(a - b)$

$6)2cx - cy - 6x + 3y = c(2x - y) - 3(2x - y) = (c - 3)(2x - y)$

$7) {x}^{2} - 3x + 6 - 2x = x(x - 3) - 2(x - 3) = (x - 2)(x - 3)$
