因式分解,5x^2+6xy-8y^2 x^2+(a+2)x+(a+1)
因式分解,5x^2+6xy-8y^2 x^2+(a+2)x+(a+1)

因式分解,5x^2+6xy-8y^2 x^2+(a+2)x+(a+1)
5x^2+6xy-8y^2
5x -4y
1x 2y
----------------------------
-4xy + 10xy =6xy
原式=(5x-4y)(x+2)
x^2+(a+2)x+(a+1)
x a+1
x 1
----------------
(a+1)x + x =(a+2)x
原式=(x+a+1)(x+1)

(x+2y)(5x-4y)
(x+1)(x+a+1)
