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
