Answer:

<u>-1133</u>

Step-by-step explanation:

<u>Formula for nth term</u>

  • aₙ = a + (n - 1)d

<u>Finding d</u>

  • d = -45 - (-28)
  • d = -45 + 28
  • d = -17

<u>Solving for a₆₆</u>

  • a₆₆ = -28 + 65(-17)
  • a₆₆ = -28 - 1105
  • a₆₆ = <u>-1133</u>

Factor completely. Remember to look first for a common factor. If a polynomial is prime, state this.
Yakvenalex [24]
This one is prime.  The sum of two squares doesn't factor.

The more interesting case is q^2-1, which factors into (q-1)(q+1).
