Common factor (x + Y-Z) (X-Y + Z) + (y-x-z) (Y-X + Z) This is factorization

Common factor (x + Y-Z) (X-Y + Z) + (y-x-z) (Y-X + Z) This is factorization

(x+y-z)(x-y+z)+(y-x-z)(y-x+z)
=-(x+y-z)(-x+y-z)+(y-x-z)(y-x+z)
=(y-x-z)
=2(y-x-z)(-x+z)

The square of (2x + y) and the square of - (x + 2Y) extract the common factor~

Square of (2x + y) - (x + 2Y)
=4X + 4xy + y-x-4xy-4y
=3x-3y
=3 (X-Y)
=3（x+y）（x-y）

The common factor of decomposition factor X & # 179; y-4xy & # 179; 5x (a + b) - Y (B + a) is decomposition factor: 3 (X-2) - 2x (X-2)
3(x-2)-2x(2-x)

The common factor of X & # 179; y-4xy & # 179; = XY (X & # 178; - 4Y & # 178;) = XY (x + 2Y) (x-2y) 5x (a + b) - Y (B + a) is (a + b) = 5x (a + B) - Y (a + b) = (5x-y) (a + b) 3 (X-2) - 2x (2-x) = 3 (X-2) + 2x (X-2) = (3 + 2x) (X-2). I'm glad to answer it for you. I wish you progress in your study
