Question

PSQ is a focal chord of the parabola y 2 = 8x. If SP = 6, then write SQ.

Answer 1

Answer:

Step-by-step explanation:

Here S is not specified what is represents so I take its usual meaning as focus.

So there is property of parabola that the harmonic mean of two segments of two focal sections of focal chord made by focus as here they are SP AND SQ is equal to semi latus rectum (half of the coefficient of x in your equation).

So semi latus rectum is 4.

Which will be the harmonic mean of SP AND SQ.

Using this we get

SQ=12
