If a+b=20 and ab=50
Then find the value of a^2+b^2

Here,

a+b=20

ab=50

we know that,

⠀

According to the question,

⠀

⠀

⠀

⠀

      a² + b² = 300

Step-by-step explanation:

a + b = 20  ; ab = 50

(a +b)² = a²+ b² + 2ab

a² + b² + 2ab = (a + b)²

a² + b² + 2*50 = (20)²

a² + b² + 100 = 400

         a² + b² = 400 - 100

        a² + b² = 300
