x²+10x-y²-2y+24=(x²+10x+25)-(y²+2y+1)=
=(x+5)²-(y+1)²=(x+5+y+1)(x+5-y-1)=(x+y+6)(x-y+4)
x² + 10x - y² - 2y + 24 =
= (х² + 10х) + 24 - (у² + 2у) =
= (х² + 10х) + (25 - 1) - (у² + 2у) =
= (x² + 10x + 25) - (y² + 2y + 1) =
= (x + 5)² - (y + 1)² =
= (x + 5 + (y + 1))(x + 5 - (y + 1)) =
= (х + 5 + у + 1)(х + 5 - у - 1) =
= (x + y + 6)(x - y + 4)
