How do you use the discriminant to determine the nature of the solutions given #4x^2 + 12x = 14#?
1 Answer
Therefore, the roots will be real and unequal
Explanation:
When you are solving a quadratic equation, it is very useful to know what sort of answer you will get. This can often help in determining which method to use - for example whether to look for factors or to use the quadratic formula.
A quadratic equation is written in the form
Always change to this form first
The discriminant is
The solutions to an equation are called the 'roots' and are referred to as
The value of
If
If
If
If
Note that if
Therefore, the roots will be real and unequal
