Answer:
- Prime: 3
- GCF: 1
- Factoring Trinomials: 4
- Difference of Squares: 2
- Perfect Square Trinomial (PST): 5
Step-by-step explanation:
1. Each term has an even coefficient, so a factor of 2 can be removed:
2(3x^2 +7x -15)
The remaining quadratic factor is prime.
__
2. Each of these two terms is a square, so this is the difference of two squares.
__
3. This cubic has one irrational negative real root. It is prime.
__
4. This trinomial factors in the usual way: (x +15)(x -2). It is factored by "factoring trinomials."
__
5. The magnitude of the x-coefficient is double the square root of the (positive) constant, so this is a perfect square trinomial.
