Answer:
6x² (2x - 5)
Step-by-step explanation:
12x³ - 30x²
= 6x² (2x - 5)
Answer:
C) The discriminant is 0.
Step-by-step explanation:
Since the graph of the quadratic equation has only one x-intercept, we can conclude that the quadratic has only one real root.
If a quadratic equation has only one real root, then the discriminant is 0

Answer:
F(k + 4) = k - 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Function Notation
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
F(x) = -2x + 3x - 8
F(k + 4) is x = k + 4
<u>Step 2: Find F(k + 4)</u>
- Substitute in <em>x</em>: F(k + 4) = -2(k + 4) + 3(k + 4) - 8
- Distribute -2: F(k + 4) = -2k - 8 + 3k + 12 - 8
- Combine like terms (k): F(k + 4) = k - 8 + 12 - 8
- Combine like terms (Z): F(k + 4) = k - 4
