If b is the subject of the formula, b = √(R² + 4ac).

Step-by-step explanation:

Step 1; The given equation is used to calculate the value of R with the values of a, b, and c. To make the given equation R = √(b² - 4ac) in terms of b, we need to make it such that only b is on the left-hand side while all the other variables are on the other side.

Step 2; To make b the subject of the formula we have to remove the square root on the right side, So by squaring both sides we get

R² = (b² - 4ac),

We keep b on one side, while all the other variables are taken to the other side, so we get

b² = (R² + 4ac),

to make the LHS b, we square root both sides,

b = √(R² + 4ac), in this equation, b is the subject.
