straight lines

Question

if the pairof the lines ax2+2axy+2bxy+by2=0 lie along the diameters of a circle and divide it into four sectors such that area of one of the sectors is thrice that of the other then which of the following is true??3a2-2ab+3b2=03a2-10ab+3b2=03a2+2ab+3b2=03a2+10ab+3b2=0

Dear shivanshiax2+2axy+2bxy+by2=0 lie along the diameters of a circlethese two lines are diameter of circle,only possible if the center of circle is at origin.one part is 3 times the other then angel of onle part must be thrice the otherso angel between two lines must be 45tan45 = 2√(h2-ab)/(a+b)1 = 2√((a+b)2-ab)/(a+b)(a+b)2 = 4[((a+b)2-ab)]3a2+2ab+3b2=0Please feel free to post as many doubts on our discussion forum as you can.If you find any question Difficult to understand - post it here and we will get you the answer and detailed solution very quickly.We are all IITians and here to help you in your IIT JEE & AIEEE preparation.All the best.Regards,Askiitians ExpertsBadiuddin
