Question

What is the equation of the ditectrix of the parabola y² - 10x - 10= 0?Hi

$\: \: \: \:$
​

Answer 1

Explanation:

y 2 =10x

compare with y2=10

8a=10

∴a= 10/4 = 5/2

Rquation of direction is n = -a

⇒n= −5/2

2n+5=0

It is the equation of directrix.

Hi...

Answer 2

y 2=10

compare with y 2=10

8 a =10

a=10/4 =5/2

rquation of direction is n =-a

n =-5/2

2 n+ 5=0
