Use the distributive property to remove the parentheses. -9(-u^3-4+6v^2)

36 + 9 u^3 + -54 v^2

Step-by-step explanation:

Expand the following:

-9 (-u^3 - 4 + 6 v^2)

-9 (-4 - u^3 + 6 v^2) = -9 (-4) - 9 (-u^3) - 9×6 v^2:

-9 (-4) - -9 u^3 - 9×6 v^2

-9 (-4) = 36:

36 - -9 u^3 - 9×6 v^2

-9 (-1) = 9:

36 + 9 u^3 - 9×6 v^2

-9×6 = -54:

 36 + 9 u^3 + -54 v^2
