यदि a, b, c, d गुणोत्तर श्रेढ़ी में है, तो सिद्ध कीजिए कि -
`(a+c)(c+d)=(b+c)(b+d)`

If (a+b)/(b+c)=(c+d)/(d+a) , then

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

If a ,\ b ,\ c ,\ d are in proportion, then (a) a b=c d (b) a c=b d (c) a d=b c (d) None of these

a, b are the real roots of x2+ px +1-0 and c, d are the real roots of 2 x + qx + 1 = 0 then (a-c)(h-c)(a + d)(b + d) is divisible by n) a+b+c+d (b) a +b-c-d (d) a -b-c-d (c) a-b+c-d

In triangle ABC , AD bisects angle A and intersects BC at D. If BC = a ,AC = b and AB = c, then BD = ? त्रिभुज ABC में, AD कोण A को समद्विभाजित करता है तथा BC को D पर काटता है | यदि BC = a, AC = b और AB = c है, तो BD = ?

Let the positive numbers a , b , c , d be in AP. Then a b c ,a b d ,a c d ,b c d are

If a ,b,c , d are in G.P. prove that (b + c)(b + d) = (c + a)(c+d)
