If `(m_r ,1//m_r),r=1,2,3,4,` are four pairs of values of `xa n dy` that satisfy the equation `x^2+y^2+2gx+2fy+c=0` , then the value of `m_1, m_2, m_3, m_4` is `0` b. `1` c. `-1` d. none of these

If m^2-4m+1=0 then the value of (m^3+1/m^3) is:

If (x_(r),y_(r));r=1,2,3,4 be the points of intersection of the parabola y^(2)=4ax and the circle x^(2)+y^(2)+2gx+2fy+c=0, then

Find the value of m ( m -1 )/3 - ( m -2 )/4 = 1

If M and m are the maximum and minimum values of (y)/(x) for pair of real numbers (x, y) which satisfy the equation (x-3)^(2)+(y-3)^(2)=6 , then the value of (1)/(M)+(1)/(m) is

If 5x^(3) +Mx+ N, M,N in R is divisible by x^(2) + x+1 , then the value of M +N is

Let (x_r,y_r),r =1,2,3,4 ne the points of intersection the parabola "y^2=4ax" and the circle"x^2+y^2+2gx+2fy+c=0"prove that y_1+y_2+y_3+y_4=0

If (m_r , 1/m_r), r = 1, 2, 3, 4 are concyclic points and f(x) = x , when x is rational = 1 - x , when x is irrational and a is a point where f(x) is continuous, then m_1 m_2 m_3 m_4 = (A) a (B) 2a (C) -2a (D) none of these

cosider the equation |x^(2)-2x-3|=mm in R If the given equation has four solutions,then a.m in(0,oo) b.m in(-1,3) c.m in(0,4) d.None of these
