Let x=1+(1)/(1+(1)/(1+(1)/(1+(1)/(1+(1)/(1+alpha))))). Which of the following is correct? x^(2)+x+1=0 (b) x^(2)-x+1=0( c) x^(2)+x-1=0 (d) x^(2)-x-1=0

Show that A=[53-1-2] satisfies the equation x^(2)-3x-7=0 .Thus,find A^(-1)

If f(x)=3x^(2)+24x-53 , find the negative value of f^(-1)(0) .

x^(2) + 30x + 221 = 0 y^(2) - 53y+196 = 0

The number of terms in the expansion of (x+a)^(53)+(x-a)^(53) after simplification is

|x^(2)-5x+32x-53x^(2)+x+46x+197x^(2)-6x+914x-621=ax^(3)+bx^(2)+cx+d then which of the following are correct? (a) a=0 (b) b=0(cc=0 (d) d=0

Show that the circles x^(2) + y^(2) + 2x = 0 and x^(2)+ y^(2) - 6 x -6 y + 2 = 0 touch externally at the point (1/5,3/5)

One diagonal of a square is along the line 8x-15 y=0 and one of its vertex is (1, 2). Then the equations of the sides of the square passing through this vertex are (a)23 x+7y=9,7x+23 y=53 (b)23 x-7y+9=0,7x+23 y+53=0 (c)23 x-7y-9=0,7x+23 y-53=0 (d)none of these
