Question

(x—2y)²—(2x+y)² by using identity a²—b²​

Answer 1

$\huge\boxed{\fcolorbox{cyan}{grey}{Solution:-}}$.

➡Given here.

↪(x-2y)²-(2x+y)².

= [(x-2y)+(2x+y)][(x-2y)-(2x+y)].

= (3x-y)(-x-3y).

➡We know,

♠(a²-b²)=(a+b)(a-b).

$\huge\boxed{\fcolorbox{cyan}{grey}{</u></em></strong><strong><em><u>F</u></em></strong><strong><em><u>o</u></em></strong><strong><em><u>l</u></em></strong><strong><em><u>l</u></em></strong><strong><em><u>o</u></em></strong><strong><em><u>w</u></em></strong><strong><em><u> </u></em></strong><strong><em><u>m</u></em></strong><strong><em><u>e</u></em></strong><strong><em><u>.</u></em></strong><strong><em><u>:-}}$

Answer 2

Answer:

just add it first nd then subtract the both values

identity yh h(a+b)(a-b)

where

a ka value h x - 2y

nd b ka value h 2x + y

Put the value and solve
