Math Problem Statement

Solve the quadratic equation using the Square Root Property.

left parenthesis 6 x plus 3 right parenthesis squared minus 6 equals negative 5

Solution

To solve the quadratic equation (6x+3)26=5(6x + 3)^2 - 6 = -5 using the Square Root Property, follow these steps:

Step 1: Isolate the squared term

We begin by isolating the squared term (6x+3)2(6x + 3)^2.

(6x+3)26=5(6x + 3)^2 - 6 = -5

Add 6 to both sides:

(6x+3)2=5+6(6x + 3)^2 = -5 + 6

(6x+3)2=1(6x + 3)^2 = 1

Step 2: Apply the Square Root Property

Now, apply the Square Root Property. Taking the square root of both sides of the equation gives:

6x+3=±16x + 3 = \pm \sqrt{1}

Since 1=1\sqrt{1} = 1, we have:

6x+3=±16x + 3 = \pm 1

Step 3: Solve for xx

Now, we'll solve for xx in both cases.

Case 1: 6x+3=16x + 3 = 1

Subtract 3 from both sides:

6x=136x = 1 - 3

6x=26x = -2

Divide by 6:

x=26=13x = \frac{-2}{6} = \frac{-1}{3}

Case 2: 6x+3=16x + 3 = -1

Subtract 3 from both sides:

6x=136x = -1 - 3

6x=46x = -4

Divide by 6:

x=46=23x = \frac{-4}{6} = \frac{-2}{3}

Final Answer:

The solutions to the equation are:

x=13orx=23x = \frac{-1}{3} \quad \text{or} \quad x = \frac{-2}{3}
