3.5. Alice was provided with the following trinomial; 3x² + 7x - 12x - 2x² + 10
3.5.1. provide Alice with a step by step guide on how to factorize the algebraic expression.?
To factorize the given trinomial 3x² + 7x - 12x - 2x² + 10, follow these steps:
Step 1: Combine like terms Combine the like terms in the expression: 3x² - 2x² + 7x - 12x + 10
Step 2: Simplify the expression Simplify the expression by combining the like terms: x² - 5x + 10
Step 3: Factorize the trinomial To factorize the trinomial x² - 5x + 10, you need to find two numbers that multiply to the constant term (10) and add up to the coefficient of the middle term (-5). In this case, the numbers are -2 and -3: (x - 2)(x - 3)
Therefore, the factorized form of the given trinomial 3x² + 7x - 12x - 2x² + 10 is (x - 2)(x - 3).

Step-by-Step Guide to Factorizing:
3.5.1. Group Like Terms:
- Group the terms with x² together: 3x² - 2x² = x² - Group the terms with x together: 7x - 10x = -3x
3.5.2. Factor Out the Greatest Common Factor (GCF):
From the grouped terms, the GCF is x
- x² = x - x - -3x = x - (-3)
3.5.3. Factor Out the GCF from Each Group:
- Factor out x from x²: x² = x(x) - Factor out x from -3x: -3x = x(-3)
3.5.4. Put the Factored Terms Together:
- The original expression becomes: x(x - 3) + 10
3.5.5. Check the Factorization:
- Multiply the factors together: x(x - 3) = x² - 3x - Add 10 to the product: x² - 3x + 10
Result: The factorized expression is: x(x - 3) + 10
