5n2 Simplify ——— - 28n 4 Step two:
5n2-112n Simplify ———————— + 24 4 Step three:
5n2-112n+96 Simplify ——————————— - n2 4Step four:
n2-112n+96 Simplify —————————— - 18n 4Final result:
n2 - 184n + 96 —————————————— 4
$$\frac{5n^2}{4}-28n-\frac{3n^2}{3}-18n\\\\ =\frac{5n^2}{4}-28n-n^2-18n\\\\ =\frac{5n^2}{4}-n^2-18n-28n\\\\ =\frac{5n^2}{4}-\frac{4n^2}{4}-46n\\\\ =\frac{n^2}{4}-46n\\\\$$
