Hello!

I wasn't sure where to post this thread, but I hope it is the correct place

It's about perpendicular vectors. I apologise if the question seems a bit messy, as I don't know how to use Latex, but I have tried to do my best.

The question is:

The vectors 2x and x+1 are perpendicular for two values of x.

x-3 5

a) Write down the quadratic equation which the two values of x must satisfy.

b) Find the two values of x.

I would appreciate your help,

Thanks,

Amine
