Question:

fine the product of (6×-y+z) (6×-y+z).

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

2

−12xy−14xz+15xy−18y

2

−21yz+5xz−6yz−7z

2

=10x

2

−12xy+15xy−14xz+5xz−18y

2

−21yz−6yz−7z

2

=10x

2

+3xy−9xz−18y

2

−27yz−7z

2

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

2

+3xy–9xz−18y

2

−27yz−7z
