A) Rational
B) Irrational
C) Non-real
D) Equal
Correct Answer: A
Solution :
Given equation \[2a{{x}^{2}}+(2a+b)x+b=0\], \[(a\ne 0\]) Now its discriminant \[D={{B}^{2}}-4AC\] \[={{(2a+b)}^{2}}-4.2ab={{(2a-b)}^{2}}\] Hence D is a perfect square, so given equation has rational roots.You need to login to perform this action.
