Answer:
To make x the subject of the formula x^2 + 3b = 2c, follow these steps:
1. Subtract 3b from both sides of the equation to isolate x^2 on one side:
x^2 = 2c - 3b.
2. Take the square root of both sides of the equation to solve for x:
√(x^2) = √(2c - 3b).
3. Since x can be either positive or negative, we have two possibilities:
x = ±√(2c - 3b).
Therefore, the formula x = ±√(2c - 3b) represents the solution where x is the subject. The ± symbol indicates that x can take on either the positive or negative square root of (2c - 3b).
