Bob and mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
pychu [463]
I can only give possible combination of the ages. Had the sum of the ages been given, then the 3 specific numbers would have been derived.

We need to do prime factorization of 72.

72 ÷ 2 = 36
36 ÷ 2= 18
18 ÷ 2 =  9
  9 ÷ 3 =  3
  3 ÷ 1 = 1

1 x 2 x 2 x 2 x 3 x 3 = 72

Possible combinations:

1 x 8 x 9 = 72           1 + 8 + 9 = 18
1 x 4 x 18 = 72         1 + 4 + 18 = 23
2 x 4 x 9 = 72            2 + 4 + 9 = 15
3 x 4 x 6 = 72            3 + 4 + 6 = 13

If anyone knows this please help me. Please answer only if you know. Thanks! more points for you if answered!
Sauron [17]
1a) Possible rational roots will be of the form
  ±{divisor of 10}/{divisor of 4}
Divisors of 10 are {1, 2, 5, 10}
Divisors of 4 are {1, 2, 4}

Then possible rational roots are
  {±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10}

1b) Your answer is correct.

2) One additional root will be the conjuate of the given complex root.
  5 -3i

3) If one root is 5 -√7, another will be 5 +√7. Then your polynomial is
  P(x) = (x -(5 -√7))*(x -(5 +√7)) = (x -5)^2 -(√7)^2
  P(x) = x^2 -10x +18
