因式分解:x²-3xy-10y²+x-5y
因式分解:x²-3xy-10y²+x-5y

因式分解:x²-3xy-10y²+x-5y
x²-3xy-10y²+x-5y
=(x-5y)(x+2y)+(x-5y)
=(x-5y)(x+2y+1)

x²-3xy-10y²+x-5y
=(x-5y)(x+2y)+(x-5y)
=(x-5y)(x+2y+1)

原式=(x+2y)(x-5y)+(x-5y)
=(x-5y)(x+2y+1)

因式分x²-3xy-10y²+x-5y
原式=(x-5y)(x+2y)+(x-5y)=(x-5y)(x+2y+1)

解:x^2-3xy-10y^2+x-5y
=(x-5y)(x+2y)+x-5y
=(x-5y)(x+2y+1)
