分解因式1.2a(x-y)-3b(y-x)2.-x^y-2xy+35y3.a^(x-y)-4b^(x-y)若|a+2|+

1.2a(x-y)-3b(y-x)
=2a(x-y)+3b(x-y)
=(2a+3b)(x-y)
2.-x^y-2xy+35y
=-y(x^+2x-35)
=-y(x-7)(x+5)
3.a^(x-y)-4b^(x-y)
=(x-y)(a^-4b^)
=(x-y)(a+2b)(a-2b)
|a+2|+b^-2b+1=0
|a+2|+(b-1)^=0
绝对值和平方大于等于0,相加等于0
若有一个大于0,则另一个小于0,不成立.
所以两个都等于0
所以a+2=0,b-1=0
a=-2,b=1
a^b+ab^
=ab(a+b)
=-2×(-1)
=2
(2x-5)^-(3x+1)^＞13（x^-10）
错了吧,中间是+
(2x-5)^+(3x+1)^＞13（x^-10）
4x^-20x+25+9x^+6x+1>13x^-130
-14x>-156

5.不等式分解后可为18x^+13x-154<0解不等式可成
