If a2 + b2 = 65 and ab = 8, a > b > 0, then find the value of a2 - b2.
Answer & explanation
Correct answer: option 4
a2 + b2 = 65
ab = 8
Put a = 8 and b = 1
a2 - b2 = 82 - 12
= 64 - 1 = 63
If a2 + b2 = 65 and ab = 8, a > b > 0, then find the value of a2 - b2.
Correct answer: option 4
a2 + b2 = 65
ab = 8
Put a = 8 and b = 1
a2 - b2 = 82 - 12
= 64 - 1 = 63
