Question 8: Reducing the expression \((x-3)\left(x+\frac{1}{2}\right)\) we get

A. \(x^{2}-\frac{7}{2} x-\frac{7}{2} \)

B. \(x^{2}+2 x-\frac{3}{2} \)

C. \(x^{2}-\frac{5}{2} x-\frac{3}{2} \)

D. \(3x^{2}-\frac{5}{2} x-\frac{3}{2} \)

We have

\((x-3)\left(x+\frac{1}{2}\right)=x^{2}+\frac{1}{2} x-3 x-\frac{3}{2} =x^{2}-\frac{5}{2} x-\frac{3}{2} \)
