Multiple Choice

A construction site manager is using the quadratic equation 2x2−3x=202x^2 - 3x = 20 to determine the dimensions of a workspace. After the manager divides the equation by the leading coefficient to get x2−32x=10x^2 - \frac{3}{2}x = 10, they must identify the value of 'half of bb' to proceed with completing the square. According to the method described, what is the value of half of the linear coefficient (12⋅b\frac{1}{2} \cdot b) for this equation?
