Steps:
Distribute the Negative Sign:
=-9n⁴+8+-1(9n⁴+2n³+5n²
=-9n⁴+8+−1(9n⁴)+−1(2n³)+−1(5n²)
=−9n⁴+8+−9n⁴+−2n³+−5n²
Combine Like Terms:
=−9n⁴+8+−9n⁴+−2n³+−5n²
=(−9n⁴+−9n⁴)+(−2n³+(−5n²)+(8)
=−18n⁴+−2n³+−5n²+8
Description:
The first steps is to distribute the Negative Sign, after you do it your equation will end like =−9n⁴+8+−9n⁴+−2n³+−5n². Second step is to Combine Like Terms/factors. When you do it your equation will end like=−18n⁴+−2n³+−5n²+8. And that will be the answer to simplify.
Answer: =−18n4−2n3−5n2+8
