| Topic | Polynomial Division & Manipulation |
| Type | Polynomial Expansion and Simplification |
| Difficulty | Easy -1.2 This is a straightforward polynomial expansion requiring only the distributive property (multiplying each term in the first bracket by each term in the second). It's a routine C1 algebraic manipulation with no problem-solving element, making it easier than average but not trivial since students must carefully track signs and combine like terms correctly. |

|---|---|
| \((3x-1)(2x^2-5x+3) = 6x^3-15x^2+9x-2x^2+5x-3\) | M1 |
| \(= 6x^3-17x^2+14x-3\) | A1 |
## Question 1:
$(3x-1)(2x^2-5x+3) = 6x^3-15x^2+9x-2x^2+5x-3$ | M1 |
$= 6x^3-17x^2+14x-3$ | A1 |
---1 Simplify $( 3 x - 1 ) \left( 2 x ^ { 2 } - 5 x + 3 \right)$.
