4² - (x + 8)
x = 2
<u>Step 2: Simplify</u>
- Evaluate exponents: 16 - (x + 8)
- Distribute negative: 16 - x - 8
- Combine like terms: 8 - x

- Substitute in <em>x</em>: 8 - 2
- Subtract: 6
Answer:
(3x + 1) (2x + 1)
Step-by-step explanation:
ax² + bx + c can be factored using the AC method:
1. Multiply a and c.
2. Find factors of ac that add up to b.
3. Divide each factor by a; reduce the fractions.
4. The denominator is the coefficient, the numerator is the constant.
6x² + 5x + 1
1. ac = 6 × 1 = 6
2. Factors of 6 that add up to 5: 2 and 3.
3. 2/6 = 1/3, and 3/6 = 1/2
4. The factors are 3x+1 and 2x+1.
6x² + 5x + 1 = (3x + 1) (2x + 1)

Answer:
Mistake was at Step 5
Step-by-step explanation:
Going from Step 4 to Step 5 you're supposed to:
Division first: 2 + (10 / 2)
Then Addition: 2 + 5
Solution = 7
Step 5 did addition first then division when it is supposed to do division first, then addition
