#### if 2+9=711 then find 12+3=??? number Puzzle with answer

**Answer: **915

**Solution: **

if you look at the question we have equations as

2+9=711

14+6=820;

17+11=628

then 12+3=??

**from Equation 1 **

2+9=711

2+9=(2-9)(2+9)

= 711

here we used a formula called a+b=(a-b)(a+b)

similarly for remaining equations

**Equation:2**

14+6=(14-6)(14+6)=820

**Equation:3**

17+11=(17-11)(17+11)=628

now we have 12+3=??

12+3=(12-3)(12+3)=915

**12+3=915 is the correct answer**
