# If α and β are the zeros of the quadratic polynomial , show that .

Given:α and β are the zeros of the quadratic polynomial To show: ..... (1)

solution:

one root of the given quadratic polynomial is Other root of the given quadratic polynomial is β

f(x) = x2 - p(x+1) - c

f(x) =  x2 - px - p - c

f(x) = x2 - px - (p + c)

Sum of the roots is:  Product of coefficient is:  Solve LHS of (1) to get,  +1

On substituting values, we get = -(p+c) + p + 1 = ⇒ = Hence proved
