Simplify (-7d3+5d+5d2-6d4)-(8d+5d2+2d4+3d3)

B. -8d⁴ - 10d³ - 3d

Step-by-step explanation:

Given expression

(-7d³ + 5d + 5d² - 6d⁴) - (8d + 5d² + 2d⁴ + 3d³)

Expand parentheses

(REMEMBER to change [+, -] signs when there is a [-] sign in front)

=-7d³ + 5d + 5d² - 6d⁴ - 8d - 5d² - 2d⁴ - 3d³

Put like terms together

=-6d⁴ - 2d⁴ - 7d³ - 3d³ + 5d² - 5d² + 5d - 8d

Combine like terms

=(-6d⁴ - 2d⁴) - (7d³ + 3d³) + (5d² - 5d²) + (5d - 8d)

=-8d⁴ - 10d³ + 0 - 3d

=

Hope this helps!! :)

Please let me know if you have any questions

4+n=5
