Question

If a+b = 12 and ab = 22 , then a^2 +b^2 is​

Answer 1

Answer:

a+b=12, ab=22, a^2+b^2=?

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

= 12^2-2×22

= 144-44

= 100

Answer 2

• Answer:a+b=12ab=22a ^{2} + b^{2}
• = (a + b)^2 - 2ab
• SUBSTITUTING IN THIS EQUATION:
• (12)^{2} -( 2×22) = 144 - 44=> 100
• ans=100
• I wish it helped you!
