To solve the equation \( x^2 + 4 = 53 \), follow these steps in order:
Step 1: Subtract 4 from both sides of the equation to isolate the term with \( x^2 \): \[ x^2 + 4 - 4 = 53 - 4 \implies x^2 = 49 \]
Step 2: Take the square root of both sides: \[ x = \pm \sqrt{49} \implies x = \pm 7 \]
Step 3: Write the final solutions. The solutions are: \[ x = 7 \quad \text{and} \quad x = -7 \]
