Answer 1

1)(16a-8b-100) : (-2)=-4a+4b+25

2) (16a³-8a²-100a)4a)=4a²-2a-25

3)(0,2a³b²x+20ab²x³): (10abx)=0,2ab²x(a²+100x²):(10abx)=b(a²+100x²)/50

4)(x²-16) : (16-x²)=(x²-16) : (x²-16)=-1

5)(x²-16): (4+x)=(x-4)(x+4) : (x+4)=x-4

6)(016-9x²)3x-0,4)=(0,4-3x)(0,4+3x) : (3x-0,4)=-(3x-0,4)(3x+4): (3x-4)=-(3x+0,4)

7)(x²+2x): (-x-1)=(x+1)² : -(x+1)=-(x+1)

8)(100x²-20x+1) : (1-10x)=(10x-1)² : -(10x-1)=-(10x-1)

9)(x^8-y^10): (y^5+x^4)=[(x^4)² –(y^5)²]: (x^4+y^5)=(x^4-y^5)(x^4+y^5) : (x^4+y^5)=

   =x^4+y^5

10)(x³-27) : (x²+3x+9)=(x³-3³) : (x²+3x+9)=(x-3)(x²+3x+9) : (x²+3x+9)= x-3
