Step-by-step explanation:
We have to find the product of 5x−6y−7zand2x+3y+z
The product of the given expression is calculated as,
(5x−6y−7z)×(2x+3y+z)
=(5x−6y−7z)×2x+(5x−6y−7z)×3y+(5x−6y−7z)×z
=5x×2x−6y×2x−7z×2x+5x×3y−6y×3y−7z×3y+5x×z−6y×z−7z×z
=10x

=10x

−21yz−6yz−7z
2
=10x

Hence, the product of 5x−6y−7z and 2x+3y+z=10x
