Answer :
Solving for x
Question: Solve for x: [tex]$x^2 + 7 = 16$[/tex]
Solution:
1. Isolate the x² term. Subtract 7 from both sides of the equation:
[tex]$x^2 = 16 - 7$[/tex]
[tex]$x^2 = 9$[/tex]
2. Take the square root of both sides to solve for x:
[tex]$x = \pm \sqrt9$[/tex]
[tex]$x = \pm 3$[/tex]
Final answer:
- The value of x could be either 3 or -3.
