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

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
