Okay. I'm gonna be using the questionable off one G minus F G one over G squared. Looking in. We know we have crew sign. H G times one minus sign. H T minus one plus sign. It's T times negative. Co sign. It's t divisible by one minus. Sign H t squared, which simplifies to to crow sign h t over the denominator just stays the same. We can't really simplifies any further.
