$= - 10 p^{7} + 6 p^{5} + 4 p^{3}$ $=color(green)(−10p^7) +color(blue)(6p^5) + 4p^3$

$- 6 p^{7} + 2 p^{5} - p^{3} - 4 p^{7} + 4 p^{5} + 5 p^{3}$ $−6p^7+2p^5−p^3−4p^7+4p^5 +5p^3$

combining like terms

$- 6 p^{7} - 4 p^{7} + 2 p^{5} + 4 p^{5} - p^{3} + 5 p^{3}$ $color(green)(−6p^7−4p^7) +color(blue)(2p^5 +4p^5)−p^3+ 5p^3$

$= - 10 p^{7} + 6 p^{5} + 4 p^{3}$ $=color(green)(−10p^7) +color(blue)(6p^5) + 4p^3$

How do you combine (−6p7+2p5−p3)−(4p7−4p5−5p3)(-6p^7 + 2p^5 - p^3) - (4p^7 - 4p^5 - 5p^3) ?
