Answer:
6[tex]x^{5}[/tex] + 5x² - 2x + 3
Step-by-step explanation:
Given
([tex]x^{5}[/tex] + 2x² - 4) - (-5[tex]x^{5}[/tex] - 3x² + 2x - 7)
Remove the parenthesis on the first factor and distribute the second by - 1
= [tex]x^{5}[/tex] + 2x² - 4 + 5[tex]x^{5}[/tex] + 3x² - 2x + 7 ← collect like terms
= 6[tex]x^{5}[/tex] + 5x² - 2x + 3 ← in standard form
