Answer 1

x= 4

Step 1- Add to both sides

2x^2-17=15

+17 +17

Step 2- Divide to both sides

2÷2x^2=32÷2

x^2=16

Step 3- Find the square root

√x=√16

Conclusion- x=4

Answer 2

x=4

Explanation:

`2 {x}^(2) = 15 + 17 \\ 2 {x}^(2) = 32 \\ \frac{2 {x}^(2) }{2} = (32)/(2) \\ {x}^(2) = 16 \\ \sqrt{ {x}^(2) } = √(16) \\ x = 4`
