Factor. v^2 + 12v + 20 ____

Identify Coefficients: Identify the coefficients of the quadratic expression. The quadratic expression is v^2 + 12v + 20. Here, the coefficient of v^2 (a) is 1, the coefficient of v (b) is 12, and the constant term (c) is 20.Find Multiplying Numbers: Find two numbers that multiply to the constant term (c) and add up to the coefficient of v (b). We need two numbers that multiply to 20 and add up to 12. The numbers 4 and 5 satisfy these conditions because 4 * 5 = 20 and 4 + 5 = 12.Write Factored Form: Write the factored form using the two numbers found in the previous step. The factored form of the quadratic expression is (v + 4)(v + 5), since these factors will multiply to give the original quadratic expression v^2 + 12v + 20.
