1.x^n-13x^n-1+36x^n-2
=[x^(n-2)]·(x²-13x+36)
=[x^(n-2)](x-4)(x-9)
2.x^2y^2+13xy+36
=(xy+4)(xy+9)
3.X^2+15xy+36y^2
=(x+3y)(x+12y)
4.（x+y）^2-9(x+y)-36
=(x+y-12)(x+y+3)
5.（a^2+36）^2-8(a^2+3b)-20 a^2+36应该是a^2+3b吧,
=(a²+3b-10)(a²+3b+2)
6.12x^2-5x-3
=(3x+1)(4x-3)
7.36a^2-15a+1
=(3a-1)(12a-1)

题目有错吧,
检查一下,欢迎向我追问.
