Q. Solve by Finding the\newline99) x2=49 x^{2}=49 \newlinex=7 x=7
  1. Write Equation: First, let's write down the equation we're trying to solve: x2=49x^2 = 49.
  2. Take Square Root: Now, we take the square root of both sides to solve for xx. So, x2=49\sqrt{x^2} = \sqrt{49}.
  3. Find Solutions: This gives us x=±7x = \pm 7, because both 77 and −7-7 squared equal 4949.
  4. Consider Negative Solution: But wait, the problem only says x=7x=7. We forgot the negative solution.
