Question

What are the steps for this question?

Answer 1

Let's solve the equation. To do this, we have to get x by itself. Perform the opposite of what is being done to the equation.

1. Add 5 to both sides, since 5 is being subtracted

2(x+2)^2-5=93

2(x+2)^2-5+5=93+5

2(x+2)^2=93+5

2(x+2)^2=98

2. Divide both sides by 2, since 2 is being multiplied

2(x+2)^2=98

2(x+2)^2/2=98/2

(x+2)^2=49

3. Take the square root of both sides, since x+2 is being squared

(x+2)^2=49

√(x+2)^2=√49

x+2=√49

x+2=7

4. Subtract 2 from both sides since 2 is being added

x+2=7

x+2-2=7-2

x=7-2

x=5

Answer 2

1. Add 5 to both sides

2. Divide both sides by 2

3. Take the square root of both sides

4. Subtract 2 from both sides

Explanation:

2(x+2)²-5=93

Add 5 to both sides

2(x+2)²=98

Divide both sides by 2

(x+2)²=49

Square root both sides

x+2=7

Subtract 2 from both sides

x=5
