Hi sir, for the last example question, from the original equation, x cannot be -2 and 4, but after you bring the denominator to multiply it on the RHS, x can take -2 and 4. Is it necessary to explain to students why this happens?
I feel like, the original equation where x cannot be - 2 and 4 should be better because point A and B are opposite the each other and when P is on either A or B, the Perpendicular condition is not satisfied.
That said, now I notice, x can be - 2 as long as when x =-2, y is not - 7. Means P cannot be on A and on B. Or should I say, P is undefined on A and B?
for my boys in india, gradient is what we study as slope, y2-y1/x2-x1
communication is top-notch 👍
what is a gradient ? it would be helpful if you explain
Aditya Nagesh thanks
good staff

Gradient is the slope of the lines or tan theta
nice accent
