Answer:
option d...
Step-by-step explanation:
other ones are algebric laws and multiplied function.. but option d does not show any proper identity
d) a + b = 10 is not a identity.
a) a² - b² = (a-b) (a+b)
Verification :
b) (a-b) ²= a² - 2ab + b²
→ (a-b) (a-b)
→ a(a-b) -b(a-b)
→ a² - ab - ab + b²
→ a² - 2ab + b²
c) a(a+2)= a² + 2a
→ a(a+2)
→ a² + 2a
Hence,
Option d) is not a identity.

Answer :-
d) a + b = 10 is not a identity.
Explanation :-
a) a² - b² = (a-b) (a+b)
Verification :
b) (a-b) ²= a² - 2ab + b²
Verification :
→ (a-b) (a-b)
→ a(a-b) -b(a-b)
→ a² - ab - ab + b²
→ a² - 2ab + b²
c) a(a+2)= a² + 2a
Verification :
→ a(a+2)
→ a² + 2a
Hence,
Option d) is not a identity.
