# Chapter 4 - Polynomials - 4.4 Addition and Subtraction of Polynomials - 4.4 Exercise Set: 38

$-3x^5+2x^3+\dfrac{3}{5}x^2-16$

#### Work Step by Step

Since the expression in parenthesis is preceded by a negative sign, then all terms inside the parenthesis will alter its sign when the parenthesis is removed. Hence, the given expression, $-\left(3x^5-2x^3-\dfrac{3}{5}x^2+16\right)$, is equivalent to \begin{array}{l} -3x^5+2x^3+\dfrac{3}{5}x^2-16 .\end{array}
