Algebra-1

To solve the quadratic equation , we will use the quadratic formula:

where:

(a = 1)(b = -8)(c = 20)

 

Step 1: Calculate the Discriminant

First, we calculate the discriminant (D):

 

Substituting the values:

D = 64 - 80 = -16

Since the discriminant is negative, the solutions will be complex numbers.

 

Step 2: Substitute into the Quadratic Formula

Now substitute (a), (b), and (D) into the quadratic formula:
