Answer:
Step-by-step explanation:
For
ax²+bx+c=0, the values of x which are the solutions to the equation are given by: x=−b±√b2-4ac÷2a
The discriminate is the portion of the quadratic equation within the radical:
b²−4ac
If the discriminate is:
- Positive, you will get two real solutions
- Zero you get just ONE solution
- Negative you get complex solutions
To find the discriminant for this problem substitute:
8 for a
8 for b
2 for c
8²−(4·8⋅2)⇒64−64⇒0
Because the discriminate is
0
there will be just ONE solution.
