Answer:
4 x 3 + 26 x 2 + 8x−2
Step-by-step explanation:
Distribute the Negative Sign:
=(−5x)2+2x+5+−1(−4x3−x2−6x+7)
=(−5x)2+2x+5+−1(−4x3)+−1(−x2)+−1(−6x)+(−1)(7)
=(−5x)2+2x+5+4x3+x2+6x+−7
=25x2+2x+5+4x3+x2+6x+−7
Combine Like Terms:
=25x2+2x+5+4x3+x2+6x+−7
=(4x3)+(25x2+x2)+(2x+6x)+(5+−7)
=4x3+26x2+8x+−2
Answer:
=4x3+26x2+8x−2
