Question

my question is plezzz answer

Answer 1

ax2 + bx + c

When the roots are p and q, the same quadratic becomes:

a(x−p)(x−q)

Is there a relationship between a,b,cand p,q ?

Let's expand a(x−p)(x−q):

a(x−p)(x−q) 
= a( x2 − px − qx + pq ) 
= ax2 − a(p+q)x + apq

now your question

p(x)= x square- (k-6)x + (2k+1)


roots for the eqn. are α,β

condition:
α+β = αβ

k-6 = 2k+1
k = -7
