can help mi find the roots of
Qn1. 6 - (x^2/10) - (4/x) = 0
Qn2. x^2 + 5x -70 + (40/x) = 0
note. they are non integers.
and
the coordinates of a point are (4 , 2.4) and the equation of the curve is y=5 - (x^2/10) - (4/x)
find the gradient of the point.(using differentiation)
Q1 roots = 7.388, -8.06, 0.6717
Q2 roots = 5.83, -11.43, 0.6
y = 5 - (x^2/10) - (4/x)
dy/dx = -x/5 + 4/x^2 when x = 4, dy/dx = -0.55
