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(-4x^4+6x^2+\dfrac{3}{4}x-8\right) $, is equivalent to \begin{array}{l} 4x^4-6x^2-\dfrac{3}{4}x+8 .\end{array}
