Question

a metre ruler is balanced at the 80cm mark when the height of 100g is hung from 1 end. Draw and show the diagram​

Answer 1

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:
