If both roots of x2 -32x + c 0 are prime numbers then possible values – InterviewSolution

1.

If both roots of x2 -32x + c 0 are prime numbers then possible values of c are [16(A) 60(B) 87(C) 247(D) 231

Answer»

There are only two such combinations.

3+29=32 & 13+19=32

Now, c is the product of both roots. Then

c = 3*29 = 87 & c = 13*19 = 247
