# How do you find the discriminant, describe the number and type of root, and find the exact solution using the quadratic formula given #x^2-16x+4=0#?

##### 1 Answer

Equation has two real roots

Two roots are

#### Explanation:

Given quadratic equation is

Formula to find the roots

Where a, b, c are the coefficients of

Term

If the **discriminant** term is

a) Positive - **both** the roots are **real**

b) Zero - **one real** solution

c) Negative - **two complex** solutions

Hence the equation has two real roots.
