Answer : one of the factor is (2h+1)
![-2h^2 - 15h - 7](https://img.qammunity.org/2019/formulas/mathematics/college/zvv48g8w58jr3dggqu94f5ecg2egu5fl21.png)
LEts factor the given expression
WE have negative in common
so we factor out negative
![-(2h^2 + 15h + 7)](https://img.qammunity.org/2019/formulas/mathematics/college/k79nud1ap0tn03k3424mly6cwhzygre15m.png)
Now we multiply 2 and 7 = 14
We find out two factors whose product is 14 and sum is 15
1 times 14 = 14
1 + 14 = 15
So two factors are 1 and 14
Now split the middle term 15h using factors 1 and 14
![-(2h^2 + 1h + 14h + 7)](https://img.qammunity.org/2019/formulas/mathematics/college/ujf31e8brqjjr4cdpkgtf32zvbfi18id40.png)
We group first two terms and last two terms and factor out GCF
![-(2h^2 + 1h) + (14h + 7)](https://img.qammunity.org/2019/formulas/mathematics/college/dot1hy03y0osojq5yj9up61cbw0fotcdm2.png)
![-h(2h+ 1) + 7(2h + 1)](https://img.qammunity.org/2019/formulas/mathematics/college/5lc4dyee0lneuonrji46l1bm49et6pu0rq.png)
![- (2h+ 1)(h+7)](https://img.qammunity.org/2019/formulas/mathematics/college/ynxitpykt041rfeww4l4p3wocnehblc2zf.png)
So one of the factor is (2h+1)
