The quicker the better in fact


y = (x+1)(x-5)


slope o& tangent = 2x-4

At x =6, tangent slope =6*3-4=8

Normal slope =-1/8

Hence, normal eqn.


or, x+8y=62

X-intercept: (62,0)


hence, area of the triangle formed by normal and co-ordinate axes

=(1/2)*62*(62/8)=240.25. Ans.


pl rate the answer 5 stars if no clarification is needed.
