Question

(a²+b²)x²-2(ac+bd)x+(c²+d²)=0 দ্বিঘাত সমীকরণের বীজদ্বয় সমান হলে, প্রমাণ করি যে,a/b=c/d​

Answer 1

Answer:

The given quadratic equation is (a2 + b²)x2 -2(ac + bd)x + (c² + d²) = 0.

If the roots of given quadratic equation are equal, then its discriminant is zero.

.:. D = [−2(ac + bd)²] − 4(

⇒ 4(a²c² + b²d² + 2abcd) —

-

⇒ 4(a²c² + b²d² + 2abcd

⇒2abcd-a²d²b²c² = 0

⇒a²d² + b²c² - 2abcd = 0

⇒ (ad - bc)² = 0

⇒ ad-bc = 0

→ ad = bc
