Answer 1

Answer:

Answer:

6x^2 y^2 +1xyz-15z^2

Answer 2

Answer:

$(2x - 3z)(4x + 5z)= 8x^2 - 2xz - 15z^2$

Step-by-step explanation:

Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac

(2x - 3z)(4x + 5z)​

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

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

$= 8x^2 + 10xz - 12xz - 15z^2\\= 8x^2 + (10 - 12)xz - 15z^2\\= 8x^2 + 2xz - 15z^2$
