Answer

$F’(x) = 2x-5-\frac{3}{2}x^{-\frac{5}{2}}$

Work Step by Step

$ F(x) = \frac{x^{4}-5x^{3}+x^{\frac{1}{2}}}{x^{2}}$ $Quotient Rule: $ $F’(x) = \frac{x^{2}(4x^{3}-15x^{2}+\frac{x^{-\frac{1}{2}}}{2})-(x^{4}-5x^{3}+x^{\frac{1}{2}})(2x)}{x^{4}} $ $ Expand: $ $ F’(x) = \frac{(2x^{5}-5x^{4}-\frac{3x^{\frac{3}{2}}}{2})}{x^{4}} $ $ Simplify: $ $ F’(x) = 2x-5-\frac{3}{2}x^{-\frac{5}{2}} $
