Verified answer
1) =(х-b)(x+b)-a(x-b)=(x-b)(x+b-a)2) =(ay-x³)(ay+x³)
3) =(c-3)²-(2x)²=(c-3-2x)(c-3+2x)
4)=(2c+5)²-(3a)²=(2c+5-3a)(2c+5+3a)
5)=(y²x+xy²+4yx)+(x+y+4)=xy(x+y+4) + (x+y+4)=(x+y+4)(xy+1)
6)=(3x²+2x-xy) - (2y²-y³+3xy²)=x(3x+2-y) -y²(2-y+3x)=(3x-y+2)(x-y²)
7)= (x²+x-xy)-(y²-y³+xy²)=x(x+1-y) - y²(1-y+x)=(1-y+x)(x-y²)
8) =(a²x+ax²+2ax)+(a+x+2)=ax(a+x+2)+(a+x+2)=(a+x+2)(ax+1)
