<u>Step 1: Define</u>
2x³ - x² - 4x + 9
x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 2(3)³ - 3² - 4(3) + 9
- Exponents: 2(27) - 9 - 12 + 9
- Multiply: 54 - 9 - 12 + 9
- Subtract: 45 - 12 + 9
- Subtract: 33 + 9
- Add: 42
Answer:
2,4,6,8,12,16
Because it is 2 times 3 equals 6
2 times 1 equals 2
2 times 2 equals 4
2 times 8 equals 16
2 times 3 equals 6
2 times 4 equals 8
2 times 6 equals 12
and they are all a factor of 2

Use standard Division to get your answer but in most classes you won’t be given an answer that big and you should use s calculator
Answer: <em>x</em> = -2
Work:
Convert 216 = 6³
Therefore: 6³ = 6^(4x+11)
⇒ Bases cancel out:
3 = 4x + 11 ⇒ Subtract 11 from both sides
-8 = 4x ⇒ Divide both sides by 4
x = -2
