please answer this fast​

Answer 1

Answer:

6x² + 12y² + 17xy - 25xz

Step-by-step explanation:

(2x + 3y) (3x + 4y - 5z)

= 6x² + 8xy - 10xz + 9xy + 12y² - 15yz

= 6x² + 12y² + 8xy + 9xy - 10xz- 15yz

= 6x² + 12y² + xy (8 + 9) - xz (10 + 15)

= 6x² + 12y² + 17xy - 25xz

Answer 2

-10xz-15yz+6x^2+17xy+12y^2
