A) find the value of the discriminant
B) describe the number and type of roots


Since a = -3, b = -7, and c = 2-6 = -4, they are all negative.
This gives a = -3, b = -7, and c = -4.
That is from the equation -3x -7x - 4 = 0.

The discriminant is b - 4ac. These values make it 49 - 48 = 1.
This makes the two factors be (71)/-6.

That gives 8/-6 and 6/-6, and these reduce to -4/3 and -1.

Looking at (x + 4/3)(x + 1) gives x + 7x/3 + 4/3.
Multiplying by -3 gives -3x - 7x - 4, which is what we started with.

Thus, it can be said there are two distinct real roots.
