Final answer:
To solve the equation (r - 1/2)^2 = 34, take the square root of both sides and solve for r.
Step-by-step explanation:
The given equation is (r - 1/2)2 = 34.
To solve for r, we can take the square root of both sides of the equation.
(r - 1/2) = ±√34
Now, we solve for r by adding 1/2 to both sides.
r = 1/2 ± √34
Therefore, the number is 1/2 and the coefficient is √34.
