Question

if a+b=3 and ab =2 find the values of a^+b^​

Answer 1

Your question is Incomplete.

I'm taking it as a²+b².

Given:-

a+b = 3

ab = 2

To find:-

a²+b²

Solution:-

We know that,

(a+b)² = a²+b²+2ab

Using this identity,

(3)² = a²+b² + 2(2)

9 = a² + b² + 4

a²+b² = 9-4

a²+b² = 5

Answer :- a²+b² = 5

Hope it helps and the Question was to find a²+b².
