Question

verify the identity a-b whole square equal to a square minus 2 a b + b square for a=9 and b= 4​

Answer 1

Step-by-step explanation:

(a-b)²=a²-2ab+b²

(9-4)²=9²-2(9)(4)+4²

5²=81-72+16

25=97-72

25=25

Therefore LHS =RHS

hence verified

Answer 2

if a = 9

and b = 4

(a-b)sq. = (a)sq -2(a×b) + (b)sq

(9-4)sq. = (9)sq -2(9×4)+ (4)sq

5sq. = 81 - 2× 36 + 16

25 = 81 - 72 + 16

= 81 + 16 - 72

= 97 - 72

25 = 25

LHS = RHS

hence it is verified
