Answer:

x = .1  (or as 2/20, 1/10)

Step-by-step explanation:

okay lets start with simplifying 4x^2,    4x * 4x = 16x right?

so lets plug that in with the equation.    16x + 4x - 2 = 0

simplify by adding the 4x with the 16x,    20x - 2 = 0

now add 2 to both sides, 20x = 2

now divide both sides by 20, x = .1  (or as 2/20, 1/10)
