因式分解2x2-7xy-22y2-5x+35y-3 x2-3xy-10y2+x+9y-2

因式分解2x2-7xy-22y2-5x+35y-3 x2-3xy-10y2+x+9y-2
2x^2-7xy-22y^2-5x+35y-3
=(2x-11y)(x+2y)-5x+35y-3
=(2x-11y)(x+2y)+(x+2y)-(6x-33y+3)
=(x+2y)(2x-11+1)-3(2x-11y+1)
=(2x-11y+1)(x+2y-3)
x^2-3xy-10y^2+x+9y-2
=(x+2y)(x-5y)+2x+4y-x+5y-2
=(x+2y)(x-5y)+2(x+2y)-(x-5y+2)
=(x+2y)(x-5y+2)-(x-5y+2)
=(x+2y-1)(x-5y+2)
