The sum of two numbers is 8 and the sum of their squares is 120. Find the product of the two numbers.	Pick:
A) 25
B) 24
C) 23
D) 21
E) 28

Rationale: let a and b be the two numbers ( a + b ) ^ 2 = a ^ 2 + 2 ab + b ^ 2 given ( a + b ) = 8 a ^ 2 + b ^ 2 = 120 so , 8 ^ 2 = 120 + 2 ab 2 ab = 120 - 64 2 ab = 56 ab = 28 ans e
Answer: E
