# 21) Find the equation of the normals to the curve which are parallel to the line Equation of given curve is Parellel to line means slope of normal and line is equal
We know that, equation of line
y= mx + c
on comparing it with  our given equation. we get, Slope of tangent = We know that   Now, when x = 2, and
When x = -2 , Hence, the coordinates are (2,18) and (-2,-6)
Now, the equation of at point (2,18) with slope  Similarly,  the equation of at point (-2,-6) with slope  Hence, the equation of the normals to the curve which are parallel
to the line are x +14y - 254 = 0  and  x + 14y +86 = 0
