Both roots of the quadratic equation x2−63x+k=0 are prime numbers. The number of possible values of k is
Both the roots of x2 - 63x + k = 0 are prime numbers. Then the sum of the digits of k is
If 3 is root of the quadratic equation x2−x+k=0, find the value of p so that the roots of the equation x2+k(2x+k+2)+p=0 are equal.
