16-(2a+36)^2=(4-2a-36)(4+2a+36)
=(-2a-32)(2a+40)=-4(a+16)(a+20)
-36x^2+12xy-y^2=(-6x+y)(6x-y)
4x(a-b)-8y(b-a)=4(a-b)(x+2y)
(x^2-5)^2+8(x^2-5)+16
=(x^2-1)^2
还有两道计算题
2x^2y×(-8y^2)+4x^y×5y^2
=(20x^y-16x^2y)y^2
=4y^2x^y(5-4x^y)
2(x+5)(x-4)-3(X-6)(X+1)
=2(x^2+x-20)-3(x^2-5x-6)
=-x^2+17x-22?

=(4+2a+36)(4-2a-36)=(2a+40)(-2a-32)=-4(a+20)(a+16)
=-(6x-y)^2
=(a-b)(4x+8y)=4(a-b)(x+2y)
=(x^2-5+4)^2=[(x-1)(x-4)]^2
