**Chaz**, Thursday, March 13, 2008 at 9:20pmmeant +9 and then do the rest.

**Reiny**, Thursday, March 13, 2008 at 9:21pmyes, you are right, but you should have maintained your equation.

20x^2+3x+9 = 0

(4x+3)(5x-3) = 0

You could have tested your answer by expanding it to get back the

20x^2+3x+9 = 0

**Reiny**, Thursday, March 13, 2008 at 9:23pmoops, just looked at your second line and assumed you would have had that one correct,

Chad is correct above.

**Tim**, Thursday, March 13, 2008 at 9:36pmSo my second line should be:

20x^2-27x+9=0

**Reiny**, Thursday, March 13, 2008 at 9:38pmyes, and it factors to

(5x-3)(4x-3) = 0

test the answer by expanding it

**Tim**, Thursday, March 13, 2008 at 9:56pmSorry, I put and = when it should have been a +! Is the one below right?

20x^2-12x+15x-9

20x^2-12x+15x-9

= 20x^2+3x-9

= (4x+3)(5x-3)
