\huge\mathbb{SOLUTION}}

\bold{(a+b)^2=a^2+2ab+b^2}}

Draw a square with the side a+b,I,e 3+2

L.H.S area of whole square

\large\bold{=(3+2)^2=5^2=25}

R.H.S. = area of square with 3units + area of square with side 2 units + area of rectangle with sides 3,2units+area of rectangle with sides 2,3 units

\large\bold{=3^2+2^2+3*2+3*2}

\large\bold{=9+4+6+6=25}

\large\bold{l.h.s=r.h.s}

Therefore hence the identity is verified

Answer:

verification

Explanation:

a=3 b=2

solution:[a+b]²=[a]²+[b]²+2ab

            =[3+2]=[3]²+[2]²+2×3×2

            =9+4+12

            =25
