Factor. j^2 + 5j + 6 ____

Identify Coefficients: Identify the coefficients of the quadratic expression. The quadratic expression is j^2 + 5j + 6. Here, the coefficient of j^2 (a) is 1, the coefficient of j (b) is 5, and the constant term (c) is 6.Find Multiplying Numbers: Determine two numbers that multiply to c (6) and add up to b (5). We need to find two numbers that multiply together to give 6 and add together to give 5. The numbers 2 and 3 satisfy these conditions because 2 * 3 = 6 and 2 + 3 = 5.Write Factored Form: Write the factored form using the two numbers found in the previous step. The factored form of the quadratic expression is (j + 2)(j + 3), because when we expand this, we get j^2 + 2j + 3j + 6, which simplifies to j^2 + 5j + 6.
