Question

if a, b are the roots of the eq ax^2+bx+ c=0,then the quadratic eq whose roots are a+b ,ab are​ ​

Answer 1

Step-by-step explanation:

a+ab+b are the root of ax2+bx+c=0ax2+bx+c=0

⇒a+b=−ba⇒a+b=-ba

α.Bη=caα.Bη=ca

Quadratic equation whose roots are α+βα+β, and αβαβ is x2−(−bc+ca)x+−ba×ca=0x2-(-bc+ca)x+-ba×ca=0.

x2+(b−ca)x−bca2=0x2+(b-ca)x-bca2=0
