4. Find the difference. (9a^4 + 2a^2 + 5) - (16a^4 - 7a^2 + 1) A) 25a^4 - 5a^2 - 4 B) -7a^4 - 5a^2 + 6 C) 25a^8 + 9a^4 + 6 D) -7a^4 + 9a^2 + 4
Vocaloid

start by combining like terms 9a^4-16a^4 = ?
anonymous
  • anonymous
9a^6 ?
Vocaloid

right, but I asked 9-16, not 16-9
anonymous
  • anonymous
9-16= -7
Vocaloid
  • Vocaloid
good! so, any ideas on what 9a^4 - 16a^4? (remember, when we add/subtract terms with exponents, the exponents don't change)
Vocaloid
  • Vocaloid
still there?
anonymous
  • anonymous
@Vocaloid Hey, sorry I'm back now
Vocaloid
  • Vocaloid
good, so 9a^4 - 16a^4 = ?
anonymous
  • anonymous
@Vocaloid -7a^4
Vocaloid
  • Vocaloid
good, now work on the a^2 term 2a^2 + 7a^2 = ?
anonymous
  • anonymous
-7a^-4 + 9a^2 + 4
Vocaloid
  • Vocaloid
good!!
