Hi, i have a question worth 2 marks. And its obviously so simple, its totally evading me

Show that y1(x) = x and y2(x) = x^2 are linearly independent

I was thinking along the lines of Wronskian but i get the answer to be x^2. And of the 2 equations to be linearly independent using Wronskian the

answer must not equal 0. So im confused.

Thanks in advance for any help
