Question

expand (2x²y+5z²)² send me correct answer plz​

Answer 1

Answer:

answer is 2x²+20x²yz²+5z²

Step-by-step explanation:

here we use the identity (a+b) ²=a²+2ab+b²

here 2x²+5z²

=2x²y+2(2x²y×5z²)+5z²

2x²y+20x²yz²+5z²

Answer 2

$\huge \mathscr{\orange {\underline{\pink{\underline {Answer:-}}}}}$

We Know the Algebraic Identity,

(a+b+c) = a²+b²+c²+2ab+2bc+2ca

Here,

a = 2x ,

b = -y ,

c = z ,

[ 2x + ( - y ) + z ]²

= (2x)²+(-y)²+z²+2(2x)(-y)+2(-y)z+2z(2x)

= 4x² + y² + z² - 4xy - 2yz + 4zx.

I Hope it's Helpful.
