Question

Find the condition if the sum of the roots of quadratic equation ax^2 – bx – c = 0 is equal to the product of its roots

(please write the steps, and i'll mark as brainliest please)

Answer 1

Step-by-step explanation:

Let x & y be the roots of f(x) => ax²-bx-c = 0

wkt , x+y = -(-)b/a => b/a

xy = -c/a

so, the by the given condition we can take ,

x+y = xy

b/a = -c/a

b = -c ----(1)

so the condition is b+c = 0..:);)
