Question 93699
factor- 
7x^2 + 34x - 5
:
You can see that 7 only has 1 & 7 as factors
Also 5 has only 5 and 1 as factors
:
You know it will be this because the middle term is 34 (7*5):
(7x__ 1)(x___5)
:
Now just find the signs that will make this thing work
(7x - 1)(x + 5)
:
Check it by FOILing these factors; 7x^2 + 35x - 1x - 5 = 7x^2 + 34x -5
