The sides of A B C satisfy the equation 2a^2+4b^2+c^2=4a b+2a cdot Then the triangle a)isosceles the triangle b)obtuse c) B=cos^(-1)(7/8) d) A=cos^(-1)(1/4)

Let alpha,beta be the roots of the quadratic equation a x^2+b x+c=0 and delta=b^2-4a cdot If alpha+beta,alpha^2+beta^2alpha^3+beta^3 are in G.P. Then a. =0 b. !=0 c. b =0 d. c =0

Let alpha,beta be the roots of the quadratic equation a x^2+b x+c=0 and delta=b^2-4a cdot If alpha+beta,alpha^2+beta^2alpha^3+beta^3 are in G.P. Then a. =0 b. !=0 c. b =0 d. c =0

If the roots of the equation a x^2+b x+c=0 are of the form (k+1)/k and (k+2)/(k+1) ,then (a+b+c)^2 is equal to 2b^2-a c b. a 62 c. b^2-4a c d. b^2-2a c

Factorize: a^2+4b^2-4a b-4c^2
