Answer:

x=4

Step-by-step explanation:

[tex]2 {x}^{2} = 15 + 17 \\ 2 {x}^{2} = 32 \\ \frac{2 {x}^{2} }{2} = \frac{32}{2} \\ {x}^{2} = 16 \\ \sqrt{ {x}^{2} } = \sqrt{16} \\ x = 4[/tex]

Answer:

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
