Question

a square + b square
= 13
and
ab = 6
find the value of (a+b)​

Answer 1

Answer:

(a+b)= 5 is the answer.....

(a+b)^2= a^2 +b^2 +2ab

= 13+12

=25

Hence,(a+b)=5

Answer 2

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2

(a+b)^2=a^2+b^2+2ab

(a+b)^2=13+2×6

(a+b)^2=13+12

(a+b)^2=25

(a+b)^2=5^2

(a+b)=5
