Answer:

1. 6x^2(9 + 7x - 5x^2)

2. 12xyz

3.  2(15xy – 6x +5y – 2)

4. ( 1 – xy)(z – 19)

5. 4(( 5x - 2y)( 5x - 2y))

6. (4x^2 + y^2)( 2x + y)( 2x – y)

7. ( x + 2)( x + 4)

8. (7y + 1)(7y –1)

9. 2( x + y + z)

10. 2(y2 + 7y + 10) / (y + 5)

Step-by-step explanation:

1. 54x2 + 42x3 – 30x4

  6x^2(9 + 7x - 5x^2)

2. 2x2yz + 2xy2z + 4xyz

    4xyz + 4xyz + 4xyz

    12xyz

3. 30xy – 12x + 10y– 4

   2(15xy – 6x +5y – 2)

4. z – 19 + 19xy – xyz

   z – xyz – 19 + 19xy

   z( 1 – xy) – 19(1 – xy)

   ( 1 – xy)(z – 19)

5. 100x2 – 80xy + 16y2

    4( 25x^2 – 20xy +4y^2)

    4( 25x^2 – 10xy – 10xy +4y^2)

    4( 5x( 5x - 2y) – 2y( 5x - 2y)

    4(( 5x - 2y)( 5x - 2y))

6. 16x4 – y4

    (4x^2 + y^2)(4x^2 – y^2)

    (4x^2 + y^2)( 2x + y)( 2x – y)

7. x2 + 6x + 8

   x^2 + 2x + 4x +8

   x( x + 2) + 4( x + 2)

   ( x + 2)( x + 4)

8. 49y2 – 1

   (7y + 1)(7y –1)

9. 10(x^3y^2x^2 + x^2y^3z^2 + x^2y^2z^3) /5x^2y^2z^2.

    2(x^3y^2x^2 + x^2y^3z^2 + x^2y^2z^3)ω

    2x^2y^2z^2( x + y + z) / x^2y^z^2

    2( x + y + z)

10. 12(y2 + 7y + 10) / 6(y + 5)

     2(y2 + 7y + 10) / (y + 5)

Answer:

(10) Answer:

10 (x3y2x2+x2y3z2+x2y2z3)=2(x3yz3)

Step-by-step explanation:

10x3y2x2÷5x2y2z2+10x2y3z2÷5x2y2z2+10x2y2z3÷5x2y2z2=

2x3z2+2y+2z then

2 (x3yz3)
