Question

0.5(x^4 − 9) + 17 Combine like terms.

Answer 1

Hello from MrBillDoesMath!

Answer:

0.5 x^4 + 12.5

Discussion:

Only the constant terms are "like" and can be combined. Nothing combines with x^4.

0.5 ( x^4 - 9) + 17 =

0.5 x^4 -  0.5 (9) + 17 =               as 0.5(9) = 4.5

0.5x^4  -  4.5 + 17 =

0.5 x^4 + 12.5

Thank you,

MrB
