First you take 8 common which is the highest number that can divide both the nimbers, then u can also take t common...now taking a negative common is up to you. so I did all this in the second step. Then you just set it equal to 0. t=0 and 15/2
If you want to learn to factor fractions, it's easy for example -16×(t²+15/2t) now -16×t² is -16t² , but -16×15/2t, first you factor -16 with number that is above the line, it would be -16×15t, and then divide with a number below the line so it's -16t²-(16×15)/2t= -16t²-120t and next solve 0=-16t²-120t 0=8t²(2t-15) 8t²=0. 2t=15 t1=0. t2=15/2 there are two solutions
