Answer:

(-b/c)   and   (c/a)

Step-by-step explanation:

    It has been given an identity that sum and product of roots are given by S and P , in k(x^2 - Sx + P) = 0.

So,

⇒ ax^2 + bx + c = 0

⇒ a(x^2 - (-b/a)x + (c/a)  ) = 0

Hence, sum of roots = -b/a

           product of root = c/a

Proof:

Roots are given by quadratic equation:

             and for the sum and product  u can use quadratic formula

Answer 2

Answer:

these are called the roots of the quadratic equation

Step-by-step explanation:

ax^2 +bx+c=0,the sum of its roots =b/a and the product of its roots =c/a .A quadratic equation may be expressed as a product of two binomials
