Solving for 'd' in the Equation (d + 3)^2 = 7
This article will guide you through the process of solving the equation (d + 3)^2 = 7 for the variable 'd'.
Understanding the Equation
The equation presents a squared term, meaning we need to get rid of the square before isolating 'd'. We can achieve this by applying the square root to both sides of the equation.
Solving for 'd'

Take the square root of both sides: √[(d + 3)^2] = ±√7 This results in: d + 3 = ±√7

Isolate 'd': d = 3 ±√7
Final Solution
Therefore, the solutions for 'd' in the equation (d + 3)^2 = 7 are:
 d = 3 + √7
 d = 3  √7
These are the two possible values for 'd' that satisfy the given equation.
