Answer:

Solve with the Quadratic Formula

Let's solve your equation step-by-step.

(3x)2+4x+1=0

Step 1: Simplify both sides of the equation.

9x2+4x+1=0

For this equation: a=9, b=4, c=1

9x2+4x+1=0

Step 2: Use quadratic formula with a=9, b=4, c=1.

x=

−b±√b2−4ac

2a

x=

−(4)±√(4)2−4(9)(1)

2(9)

x=

−4±√−20

18
