General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define</u>
-8x + 4 < -4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4 on both sides: -8x < -8
- Divide -8 on both sides: x > 1
Here we see that any value <em>x</em> greater than 1 would work as a solution.
Answer:
square roots
quadratic formula
factoring
complete the square
Step-by-step explanation:
1. In the first one, we can divide both sides by -2 and then square root it, getting x^2 = -98 so x = 7i \sqrt(2).
2. We can use the quadratic formula to find out the second one.
3. We can factor 4x^2 - 21x - 18 = 0 and get (x + 6)(4x - 3).
4. In the last one, we can complete the square, getting (x + 9)^2 + 16.
