Three and seven twelfths
8 3/4 = 35/4 = 210/24
5 1/6 = 31/6 = 124/24
(210-124)/24
86/24
43/12
3 7/12
For this case we have that by definition, the discriminant of a quadratic expression is given by:
If the discriminant is less than zero then the expression has two different complex roots.
In this case we have the following expression:
So we have to:
The discriminant is given by:
Then, if we want two complex roots it must be fulfilled that:
Thus, the expression has two complex roots for all values greater than 4.

Lol i dont know the answer but i love your profile pic again sorry
To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x. To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:
10x + 3ax - 5ax = -7a + 35
Factoring x out of the left side, we get:
x(10 - 2a) = 7(5 - a). Dividing both sides by (10 - 2a), we get:
7(5 - a)
x = ------------ = 7/2
2(5 - a)
x has the value 7/2.
