Q. 35.0( 2 Votes )

The equation of the normal to the curve y = x (2 – x) at the point (2, 0) is
A. x – 2y - 2

B. x – 2y + 2 = 0

C. 2x + y = 4

D. 2x + y – 4 = 0

Answer :

Given that y = x (2 – x)


y = 2x – x2


Slope of the tangent


Slope at (2, 0) = 2 – 4 = -2


Equation of normal:




2y=x-2


x – 2y – 2 = 0


Hence option A is correct.
