**E***, Monday, March 28, 2011 at 6:11pmx^2+6x+9

Product of the coefficients of the 1st and last terms: +9 (1x9)

Sum: +6 (middle term is always the sum)

List all the factors of 9 and determine which pair would give you a product of +9 and a sum of +6:

1,9

3,3 ✓

your answer will be (x+3)^2 or (x+3)(x+3)

Check: F.O.I.L. (x+3)(x+3)

x^2+3x+3x+9

x^2+6x+9
