Video Transcript

for exercise 56. We're going to substitute you for Z squared. So what have U squared plus. Thanks to people, U squared minus 17. U plus 17 72 equals zero. And we'll factor this out. So we have you and you and Mhm. So it can't be six times 12, eight and 9 satisfied this. So we can have U -9 -8. Products 72 and sum is -17. Now let's substitute Z squared back in where we'll have Z squared minus nine equals zero and Z squared minus eight equals zero. Here, zeke unequal plus or -3 And plus remind us to Route two. Make sure to check your answers.
