Question

Find the following product
(2x - y + 3z) (4x² + y² + 9z² + 2xy + 3yz - 6xz) ​​

Answer 1

Answer:

Step-by-step explanation:

(2x-y+3z)(4x²+y²+9z²+2xy+3yz-6xz)

(2x-y+3z)((2x)²+(y)²+(3z)²-(-y*2x)-(-y*3z)-(2x*3z)

(2x)³+(-y)³+(3z)³-(3×-y×2x×3z) [ ∵(a+b+c)(a²+b²+c²-ab-bc-ca)= a³+b³+c³-3abc]

8³-y³+27+³+18xyz Ans.
