Question

find the roots of x²+px+16 are equal and find p

Answer 1

Answer:

- 8

Step-by-step explanation:

Let the roots be 'a' and 'a'.  Comparing this with ax² + bx + c,

a = 1 ,     b = p,   c = 16  {this a is different from that in question}

 Product of roots = c/a = 16/1

                     a * a = 16  

                          a² = 16

                          a = 4

 Sum of roots = -b/a

            a + a = - p/1

            4 + 4 = - p

               - 8 = p
