प्रश्न

Find the product of 5x − 6y − 7z and 2x + 3y z

बेरीज

उत्तर

(5x − 6y − 7z) × (2x + 3y + z)

= 2x × (5x − 6y − 7z) + 3y × (5x − 6y − 7z) + z (5x − 6y − 7z)

= 10x2 − 12xy − 14xz + 15xy − 18y2 − 21yz + 5xz − 6yz − 7z2

= 10x2 − 12xy + 15xy − 14xz + 5xz − 18y2 − 21yz − 6yz − 7z2

= 10x2 + 3xy − 9xz − 18y2 − 21yz − 7z2
