Okay, so we have the following. So what use are grouping with to factor to have a which is even nine being, which is equal to negative 32 see which is you go to 15. So our key number is equal to nine times with tin, which gives me 135. So we need to numbers whose products are equal to 135 and who's sums are equal to negative 32. So two numbers we can use is negative 27 negative five. Their product is equal to 1 35 there's some is equal to negative there, too. So all we want right equation to have negative 27 thanks minus five x and our confected the 1st 2 times they have a nine x in common. So I got X minus three and then for last two terms. In fact, they're out a negative five and we get the falling. And now we see that we have an excellent is three in common, so we can factor that out and we get X minus three times nine x minus five
