Question

verify the identity.(a+b)=+2ab+bgeometrically by taking
a=3 units b=2 units.​

Answer 1

Hey there!

( i ) ( 3 - 1 )² = ( 3 )² - ( 2 ) ( 3 ) ( 1 ) + ( 1 )²

( 2 )² = 9 - 6 + 1

4 = 3 + 1

4 = 4

( ii ) ( 5 - 2 )² = ( 5 )² - ( 2 ) ( 5 ) ( 2 ) + ( 2 )²

( 3 )² = 25 - 20 + 4

9 = 5 + 4

9 = 9

Hope my answer helps!

Answer 2

4 = 4

Step-by-step explanation:

(3-1)×(3-1) = 3×3 - 2×3×1 + 1

2×2 = 9- 6+1

4=4

hence proved
