If a + b = 5 and ab = 6 , then find 3(a2 + b2).
Answer & explanation
Correct answer: option 1
If a + b = 5 and ab = 6
Then find 3(a2 + b2)
Put x = 3 and y = 2
3(a2 + b2) = 3(32 + 22) = 39
If a + b = 5 and ab = 6 , then find 3(a2 + b2).
Correct answer: option 1
If a + b = 5 and ab = 6
Then find 3(a2 + b2)
Put x = 3 and y = 2
3(a2 + b2) = 3(32 + 22) = 39
