This is not my pic because I forgot to screenshot it when I did it. Microsoft has the hardest captcha I have ever had to complete. This one looks easier but I had a similar one that on my phone the images were too small, not recognizable and were more abstract looking shapes. It was so hard, I failed like 8 times (there were several ‘rounds’) and it almost made me second guess whether I might actually be a robot lol. Luckily, there was an audio version where you have to pick from a number of melody recordings and choose the one that was a pattern. Anyone else have trouble with this?
Pretty sure 78x + 22 is f double prime of x. So f’’(x) + x simplifies to 79x + 22.
I found the other posts about XOR for solving the visual puzzle.
ah ok you’re adding the final x directly to the polynomial, that’s fine then, yes
