Please let me know if I simplified this correctly.
Simplify:
-5w squared + 23-(29-4w squared +9)
-5w squrd + 23 - 29 + 4w squrd -9
-1w to the fourth power + -15
Thanks!!!
Online "^" is used to indicate an exponent.
-5w^2 + 23 - (29 - 4w^2 + 9) =
-5w^2 + 23 - 29 + 4w^2 - 9 =
4w^2 - 5w^2 = -w^2
-w^2 - 15
