Question

find the equation whose roots are x^3+qx+r=0​

Answer 1

Answer:

please give a many points for giving u a answer and rate

Given equation, x3+qx+r=0………………(1)

a(b+c)=a(a+b+c−a)=−a2[∵sum of the roots is 0]

⟹y=−x2orx2+y=0…………..(2)

Multiplying (2) by x and subtracting from  (1), we get

(q−y)x+r=0⟹x=y−qr

Substituting value of x in (2), we get

y3−2qy2+q2y+r2=0

Answer 2

Answer:

ab+bc+ac

=abc

-q/-r

=q/r

with solutions

is the answer
