1. A quadratic equation has the general formula expressed as:

ax^2 + bx - c = 0

This equation can be solved by the quadratic formula which is expressed as:

x = ( -b (+ or -) √(b^2 - 4ac) / 2a

From the given equation,

a = 8
b = 16
c = 3

x = ( -16 (+ or -) √(16^2 - 4(8)(3)) / 2(8)
x1 = -0.21
x2 = -1.79
