Question

Multiply: (3x+ 2y+z) (x-y+2z)​

Answer 1

Step-by-step explanation:

$\left(x-y+2z\right)\left(3x+2y+z\right)$

$3x^{2}-xy+7xz-2y^{2}+3yz+2z^{2}$

Answer 2

Answer:

Solution :-

⍟︎ (3x + 2y + z) (x - 2y + 2z)

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

➞ 3x² - 6xy + 6xz + 2xy - 4y² + 4yz + xz - 2yz + z²

➞ 3x² - 4y² + z² - 6xy + 2xy + 6xz + xz + 4yz - 2yz

➞ 3x² - 4y² + z² - 4xy + 7xz + 2yz

∴ The answer of this question is 3x² - 4y² + z² - 4xy + 7xz + 2yz
