This looks like a "prime" quadratic. With trial and error trying:
(-4t )(t )
or
(-2t )(t )
you cannot get it to work. So there are no "interger" solutions. You can use the famous "quadratic equation" to get an approximation. ARe you familiar with this?

this is a quadratic formula...i need to solve it using the quadratic formula!!
ok. I assume you know the quadratic formula. It is hard to write it here. In your example, a = -4, b = -9 and c = -3. So, when you plug these in, you end up with (9+sqrt43)/8 and
(9-sqrt43)/8
this is approx: 15.56/8 and 2.44/8. These are your 2 solutions.
(9-sqrt43)/8
this is approx: 15.56/8 and 2.44/8. These are your 2 solutions.
woops...slight mistake.
It's actually: (9+sqrt33)/8 and
(9-sqrt33)/8
or 14.74/8 and 3.26/8.

-b = 9 all right
but 2a = -8
so
-b/2a = -9/8 not +
but 2a = -8
so
-b/2a = -9/8 not +
