Solve the quadratic equation: 3 (x-3) ^2-162=0

X=4.35

Step-by-step explanation:

Let's start solving

3 (x-3) ^2-162=0

Add 162 to both sides

3 (x-3) ^2=162

Square root both sides

√3 (x-3) = √162

1.73 (x-3) = 12.727

Open the bracket

1.73x-5.19=12.727

Add 5.19 to both sides

1.73x=7.5327

Divide both sides by 1.73

x=4.35
