Pls tell correct answ. And I’ll mark u branliest

Answer 1

Answer:

1.(z-19)(1-xy)

2.6x^2(5x^2+7x+9)

3. 2(xyz)

4. 6x(5x-7)

Step-by-step explanation:

1. z-xyz-19+19xy

z(1-xy)-19(1-xy)

(z-19)(1-xy)

2. 6x^2(9+7x-5x^2)

6x^2(5x^2+7x+9)

3. (10x^2y^2z^2(x+y+z))/(5x^2y^2z^2)

2(xyz)

4. 81x^3*2(25x^2-49)

(162x^3(5x+7)(5x-7))/(27x^2(5x+7))

6x(5x-7)
