Answer 1

Answer:

hope it'll help yuh....

Answer 2

Answer:

Here is the answer =>

Step-by-step explanation:

(5x+y+2z)^2

So let 5x be a

y be b

2z be c.

So (a+b+c)^2=> a^2+b^2+c^2+2ab+2bc+2ca.

NOW SUBSTITUTING THE VALUES=>

(5x+y+2z)^2= (5x)^2+(y)^2+(2z)^2+2(5x)(y)+2(y) (2z) +2(2z)(5x).

=>25x^2+y^2+4z^2+10xy+4yz+20zx.

So 25x^2+y^2+4z^2+10xy +4yz+20zx is the required answer.

HOPE IT HELPS.
