分解因式:4x²-4xy+y²-44x+22y+40分解因式:4x²-4xy+y²-44x+22y+40分解因式:4x²-4xy+y²-44

分解因式:4x²-4xy+y²-44x+22y+40
分解因式:4x²-4xy+y²-44x+22y+40

分解因式:4x²-4xy+y²-44x+22y+40
4x²-4xy+y²-44x+22y+40
=(2x-y)²-44x+22y+40
=(2x-y)²-22(2x-y)+40
=(2x-y-2)(2x-y-20)

4x²-4xy+y²-44x+22y+40
=(2x-y)²-22(2x-y)+(121-81)
=(2x-y)²-22(2x-y)+121-9²
=(2x-y-11)²-9²
=(2x-y-2)(2x-y-20)

解原式:4x²-4xy+y²-44x+22y+40
=(2x-y)²-44x+22y+40
=(2x-y)²-22(2x-y)+40
=(2x-y-2)(2x-y-20)

4x²-4xy+y²-44x+22y+40
=(2x-y)²-44x+22y+40
=(2x-y)²-22(2x-y)+40
=(2x-y-2)(2x-y-20)
