Question

a+b=12 & a^2+b^2=74
then find a & b​

Answer 1

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

(a-b)^2=74-70

(a-b)^2=4

a-b=√4

a-b=2

Now we got both the values of a-b and a+b

a+b=12

a-b=2

Now add the following

equations

2a =14

a=7

b=12-a

b=12-7

b=5

I hope this helps you and please mark me the brainliest ^_^ ^_^
