Answer:

- 3[tex]x^{4}[/tex] + 15x² - 3x

Step-by-step explanation:

Given

(5[tex]x^{4}[/tex] - 3x + 8x²) - (8[tex]x^{4}[/tex] - 7x²)

Remove the parenthesis on first and distribute second by - 1

= 5[tex]x^{4}[/tex] - 3x + 8x² - 8[tex]x^{4}[/tex] + 7x² ← collect like terms

= - 3[tex]x^{4}[/tex] + 15x² - 3x ← in standard form
