Answer 1

Respuesta:

1. -18xy-19xz-xy+9xz

  =-18xy-xy-19xz+9xz

  =-19xy-19xz+9xz

   =-19xy-10xz

2. -72ax³+85ay³-15ax³-8ax³+10ax³

    =-72ax³-15ax³-8ax³+10ax³+85ay³

    =-85ax³+85ay³

3. -72ax³+85ay³-15ax³-8ax³+10ax³

   =-72ax³-15ax³-8ax³+10ax³+85ay³

   =-85ax³+85ay³

4. 14ac-15ac²+20ac³+6ac

  =20ac³-15ac²+14ac+6ac

  =20ac³-15ac²+20ac

5. 210x⁵+90x²-110x²

  =210x⁵-20x²

6.-13ab²-26ab²

  -39ab²

7. 88x⁵+120y⁴-18x⁵

   =88x⁵-18x⁵+120y⁴

   =70x⁵+120y⁴

8.  30bc²+47bd²+20bc²

   =30bc²+20bc²+47bd²

   =50bc²+47bd²

9. -95d-15d-145f

  =-110d-145f

10. -45y⁸+68x²-15y⁸-8x²

    =-45y⁸-15y⁸+68x²-8x²

    =-60y⁸+68x²-8x²

    =-60y⁸+60x²
