Question

verify the identity (a+b)2 geometrically a=5 b=2​

Answer 1

Step-by-step explanation:

(a+b)² = (5+2)²

5² +2² + 2×5×2 = 25 + 4 + 20 = 49.

Hence verify

(a+b)²= a²+b²+2×a×b

Answer 2

Answer:

(a+b)2

but a=5, b=2

a2+2ab+b2

(5)2+2(5*2)+(2)2

25 +(2*10)+4

25+20+4

49. (1)

(5+2)2=(7)2

=49. (2)

therefore equation 1 & 2 are equal

hence prooved
