If `m` be the slope of common tangent of `y = x^2 - x + 1` and `y = x^2 – 3x + 1`. Then `m` is equal to

Sum of slopes of common tangent to y = (x^(2))/(4) - 3x +10 and y = 2 - (x^(2))/(4) is

Sum of slopes of common tangent to y = (x^(2))/(4) - 3x +10 and y = 2 - (x^(2))/(4) is

The slope of common tangents to x^(2)+4y^(2)=4 and x^(2)+y^(2)=3 is m ,then m^(2) is

If m be the slope of common tangent to the circle x^2 + y^2 = 16 and ellipse x^2/25+y^2/4=1 in the first quadrant, then 81m^8 =

If m be the slope of common tangent to the circle x^2 + y^2 = 16 and ellipse x^2/25+y^2/4=1 in the first quadrant, then 81m^8 =

Let m be slope of a common tangent to the circle x^2+y^2 = 4 and the ellipse x^2/6+y^2/3=1 , then m^2 equals ( sqrt2 =1.41 )
