If `a=b^2c`, where `a ne 0` and `b ne 0` , then `b/c`=

If ax+by -2=0 and axby =1, where a ne 0, b ne 0 , then what is (a^(2)x+b^(2)y) equal to ?

IF the difference of the roots of x^2-bx+c=0 is equal to the difference of the roots of x^2-cx +b=0 and b ne 0 , then b+c=

State whether the statement given is true (T) or false (F): If AB + 7C = 102, where B ne 0, C ne 0 , then A + B + C = 14.

If a,b,c are real, a ne 0, b ne 0, c ne 0 and a+b + c ne 0 and 1/a + 1/b + 1/c = 1/(a+b+c) , then (a+b) (b+c)(c+a) =

If A= [{:(a-b-c, 2a,2a), (2b, b-c-a, 2b),(2c, 2c, c-a-b):}] = (a +b+c) (x +a +b+c)^(2), x ne 0 " and " a +b +c ne 0 , then x is equal to

If a,x and b are in AP, a,y and b are in GP and a,z and b are in HP such that x=9z and a > 0 , b > 0 , where a ne b , b ne 0 then x^2/y^2 is _________.

If a,x,b are in AP, a,y,b are in GP and a,z,b are in HP such that x=9z and a > 0 , b > 0 , where a ne b , b ne 0 then x^2/y^2 is _________.
