Question

Subtract
Z^2-y^2+2yz from2z^2+3y^2-6yz

Answer 1

Given, two polynomial , z² - y² + 2yz and 2z² + 3y² -6yz

Let P = z² - y² + 2yz and Q = 2z² + 3y² - 6yz

now, we have to subtract P from Q

e.g., Q - P = (2z² + 3y² - 6yz) - (z² - y² + 2yz)

= 2z² + 3y² - 6yz - z² + y² - 2yz

= (2 - 1)z² + (3 +1)y² -(6 + 2)yz

= z² + 4y² - 8yz

hence, answer should be z² + 4y² - 8yz

Answer 2

HELLO DEAR,

GIVEN:-

z² - y² + 2yz and 2z² + 3y² -6yz

Let A = z² - y² + 2yz and B = 2z² + 3y² - 6yz

now, we have to subtract A from B

B - A = (2z² + 3y² - 6yz) - (z² - y² + 2yz)

= 2z² + 3y² - 6yz - z² + y² - 2yz

= (2 - 1)z² + (3 +1)y² -(6 + 2)yz

= z² + 4y² - 8yz

HENCE, answer is z² + 4y² - 8yz

I HOPE ITS HELP YOU DEAR,

THANKS
