Question 480759
49x² - 14x - 3

Factors into two binomials:
- 1st terms are factors of 49x².....could be 49x and x....or 7x and 7x
- 2nd terms are factors of -3, when you put them in, the outer and inner terms of the foil method need to combine to make -14x....only one combination works


= (7x - 3)(7x + 1) {factored into two binomials}


outer terms = 7x
inner terms = -21x
combined = -14x {the middle term, therefore these are the correct factors}
