i am very confused on how to factor will you help?

This is not an easy task, because factoring is a tough task that only becomes easier with experience. If the coefficient of x^{2} was 1, you only have to worry about working with factors of 30 to get 14 in the middle. In this case you also have to try factors of -8.

The factors of -8 are 8 and -1, or 4 and -2, or these with the signs reversed. so I tried 8 and -1:

(8x + ?)(-x +?) Can we fill in the ? with factors of 30, so that I will get 14 in the middle term

Let's try 30 and 1, 15 and 2, 10 and 3, 6 and 5

(8x + 30)(-x + 1) = -8x^{2} + 8x - 30x + 30 = -8x^{2} - 22x + 30 DID NOT WORK

(8x + 15)(-x + 2) = -8x2 + 16x - 15x + 30 = -8x^{2} + x + 30 DID NOT WORK

**(8x + 10)(-x + 3)** = -8x2 + 24x - 10x + 30 =** -8x ^{2} + 14x + 30**

**WORKED!**
