Answer
-3$x^{4}$ - 5$x^{2}$ + 7
Work Step by Step
$\frac{-42x^{6} - 70x^{4} + 98x^{2}}{14x^{2}}$ =
RECALL:
$\frac{b^{n}}{b^{m}}$ = $b^{n-m}$
So, $\frac{-42x^{6} - 70x^{4} + 98x^{2}}{14x^{2}}$ = $\frac{-42x^{6}}{14x^{2}}$ + $\frac{- 70x^{4}}{14x^{2}}$ + $\frac{ 98x^{2}}{14x^{2}}$ =
$\frac{-42}{14}$$x^{6-2}$ + $\frac{-70}{14}$$x^{4-2}$ + $\frac{98}{14}$$x^{2-2}$ =
-3$x^{4}$ - 5$x^{2}$ + 7
