Question 12: Reducing the expression (frac{1}{2}(x+1)(x-3)) we get A. (frac{1}{2} x^{2}-x-frac{3}{2} ) B. (x^{2}-x-frac{3}{2} ) C. (frac{3}{2} x^{2}-x-frac{3}{2} ) D. ( x^{2}-x-3) (frac{1}{2}(x+1)(x-3)=left(frac{1}{2} x+frac{1}{2}right)(x-3)= frac{1}{2} x^{2}-frac{3}{2} x+frac{1}{2} x-frac{3}{2}=frac{1}{2} x^{2}-x-frac{3}{2} ) =============== Go to Source
