Here's the solution to the factorization problem: 3.2.1 What is the value of b and c in the trinomial? The general form of a trinomial is ax^2 + bx + c. Comparing x^2 + x - 12 with ax^2 + bx + c: b = 1 c = -12 3.2.2 Use the table below to determine the two integers, r and s. We need two integers whose product is c = -12 and whose sum is b = 1. | Factors of -12 | Product of the two factors | Sum of the two factors | Result | | :------------- | :------------------------- | :--------------------- | :----- | | 1, -12 | -12 | -11 | No | | -1, 12 | -12 | 11 | No | | 2, -6 | -12 | -4 | No | | -2, 6 | -12 | 4 | No | | 3, -4 | -12 | -1 | No | | -3, 4 | -12 | 1 | Yes| The two integers are -3 and 4. 3.2.3 In the table below, the written explanation of the steps have been provided, show the mathematical steps for the explanations given. Factorize x^2 + x - 12 | Mathematical steps | Explanation | | :----------------- | :---------- | | x^2 + 4x - 3x - 12 | Rewrite the middle term of the trinomial using the values from the chart above. | | (x^2 + 4x) + (-3x - 12) | Group pairs of terms. | | x(x + 4) | Factor out the HCF of the first group. | | -3(x + 4) | Factor out the HCF of the second group. | | (x + 4)(x - 3) | Factor out HCF of the two terms. | | (x + 4)(x - 3) | The final factorized answer. | Send me the next one 📸
