Answer:

Step-by-step explanation:

1. add  -[tex]x^{2}[/tex]  to +[tex]x^{2}[/tex] to get x on the same side.

and then it would be [tex]2x^{2}[/tex] -7 = 1

2. add 7 on the other side then you get:

[tex]2^{2}[/tex] = 8

3. square root both sides to get rid of the squared. Then you'd get:

2x = [tex]\sqrt{8}[/tex]

4. divide both sides to have x by itself. Then you get:

x = [tex]\frac{\sqrt{8} }{2}[/tex] is your solution
